IPR044109
Name: cAMP-dependent protein kinase catalytic subunit
Type: Family
Description: The intracellular second messenger cyclic adenosine monophosphate (cAMP) exerts many of its physiological effects by activating cAMP-dependent protein kinase (PKA), which in turn phosphorylates and regulates the functions of downstream protein targets including ion channels, enzymes, and transcription factors. PKA is a tetrameric enzyme composed of a two regulatory (R) and two catalytic (C) subunits. Binding of 2 cAMP molecules to each R subunit leads to holoenzyme dissociation into the R dimer and two active subunits [, , ]. There are 4 different R sububits divided in two types, type I (RI-alpha and RI-beta), and type II (RII-alpha and RII-beta), and two main C subunits (C-alpha and C-beta) []. Type I PKA is predominantly cytoplasmic, whereas type II PKA usually associates with specific cellular structures and organelles. The intracellular organization of PKA is controlled through the association with AKAPs (A-kinase-anchoring proteins) [, , ].PKA plays a role in the regulation of diverse processes such as growth, development, memory, metabolism, gene expression, immunity, and lipolysis. The cAMP/PKA signaling pathway regulates glucose homeostasis at multiple levels including insulin and glucagon secretion, glucose uptake, glycogen synthesis and breakdown, gluconeogenesis [ ]. The cAMP/PKA pathway acts downstream of GPCRs and regulates the activities of key molecules involved in insulin secretion, including GLUT2, KATP, and Cav [].This entry includes cAMP-dependent protein kinase catalytic subunit alpha/beta (C-alpha/C-beta) from animals and their homologue, C-gamma, found in higher primates. C-gamma appears to have no function as a mature protein [ ].

Name: Protein of unknown function, Gam-like
Type: Family
Description: The Gam protein, originally characterised in Bacteriophage Mu, protects linear double stranded DNA from exonuclease degradation in vitroand in vivo[ ]. This protein is also found in many bacterial species as part of a suspected prophage. Further studies have shown that Gam is a functional counterpart of the eukaryotic Ku protein, which has key roles in DNA repair and in certain transposition events. Gam displays DNA binding characteristics remarkably similar to those of human Ku []. In addition, Gam can interfere with Ty1 retrotransposition in Saccharomyces cerevisiae (Baker's yeast). These data reveal structural and functional parallels between bacteriophage Gam and eukaryotic Ku and suggest that their functions have been evolutionarily conserved [].This family consists of several hypothetical bacterial and phage proteins of around 180 residues in length. The function of these proteins is not currently known, but they are related to the host-nuclease inhibitor protein Gam.

Centromere protein J (also known as Centrosomal-P4.1-associated-protein, CPAP), a member of the TCP10 family, plays an important role in cell division and centrosome function by participating in centriole duplication [, ]. It inhibits microtubule nucleation from the centrosome and depolymerises taxol-stabilised microtubules []. It may also be involved in the control of centriolar-microtubule growth by acting as a regulator of tubulin release []. T-complex is involved in spermatogenesis in mice [].This domain, also known as TCP and G-box, is essential for the tethering of pericentriolar material (PCM), the principle site for microtubule nucleation and anchoring. It adopts an extended single-layer antiparallel β-sheet configuration [ ]. Mutations in this region are associated with primary microcephaly [, ].

IPR022645
Name: Protein-export membrane protein SecD/SecF, bacterial
Type: Family
Description: Secretion across the inner membrane in some Gram-negative bacteria occurs via the preprotein translocase pathway. Proteins are produced in the cytoplasm as precursors, and require a chaperone subunit to direct them tothe translocase component [ ]. From there, the mature proteins are either targeted to the outermembrane, or remain as periplasmic proteins. The translocase protein subunits are encoded on the bacterial chromosome. The translocase itself comprises 7 proteins, including a chaperone protein (SecB), an ATPase (SecA), an integralmembrane complex (SecCY, SecE and SecG), and two additional membrane proteins that promote the release of the mature peptide into the periplasm (SecD and SecF) []. The chaperone protein SecB [] is a highly acidic homotetrameric protein that exists as a "dimer of dimers"in the bacterial cytoplasm. SecB maintains preproteins in an unfolded state after translation, and targets these to the peripheral membraneprotein ATPase SecA for secretion [ ]. Together with SecY and SecG, SecE forms a multimericchannel through which preproteins are translocated, using both proton motive forces and ATP-driven secretion. The latter is mediated by SecA. The structure of theEscherichia coli SecYEG assembly revealed a sandwich of two membranes interacting through the extensive cytoplasmic domains []. Each membrane is composed of dimers of SecYEG. The monomeric complex contains 15transmembrane helices. The SecD and SecF equivalents of the Gram-positive bacterium Bacillus subtilis are jointly present in one polypeptide,denoted SecDF, that is required to maintain a high capacity for protein secretion. Unlike the SecD subunit of the pre-protein translocase of E. coli, SecDFof B. subtilis was not required for the release of a mature secretory protein from the membrane, indicating that SecDF is involved in earlier translocation steps [].Comparison with SecD and SecF proteins from other organisms revealed the presence of 10 conservedregions in SecDF, some of which appear to be important for SecDF function. Interestingly, the SecDF protein of B. subtilis has 12 putative transmembranedomains. Thus, SecDF does not only show sequence similarity but also structural similarity to secondary solute transporters [].This entry represents bacterial SecD and SecF protein export membrane proteins. It is found in association with SecD and SecF proteins are part of the multimeric protein export complex comprising SecA, D, E, F, G, Y, and YajC [ ]. SecD and SecF are required to maintain a proton motive force [].

Name: Programmed cell death protein 10
Type: Family
Description: Programmed cell death 10 protein (PDCD10/CCM3) is part of the CCM complex and is required for neuronal migration [ ]. It also has roles outside of this complex [], it is crucial in vascularization and in angiogenesis as it functions in vessel permeability and stability []. PDCD10/CCM3 was originally discovered to be upregulated during granulocyte apoptosis and is thought to play a role in cell death []. However, a specific role for PDCD10 in cell survival is not clear as both pro-survival and pro-apoptotic effects have been reported [, ]. PDCD10/CCM3 contains an N-terminal dimerisation domain and a C-terminal focal adhesion targeting-homology (FAT-H) domain [].There are three CCM proteins: CCM1 (also known as KRIT1), CCM2 (also known as OSM and malcavernin) and CCM3 (also known as PDCD10). Mutations in the genes encoding CCM proteins cause cerebral cavernous malformations (CCMs), a disease characterised by dilated leaky blood vessels, especially in the neurovasculature, that result in increased risk of stroke, focal neurological defects and seizures. The CCM proteins can form a trimeric complex. They can also interact with a range of signaling, cytoskeletal and adaptor proteins that may account for their roles in a range of basic cellular processes including cell adhesion, migration, polarity and apoptosis [ ].

Name: Mitochondrial ribosomal protein S7, plants
Type: Family
Description: uS7, also known as ribosomal protein S7 (RPS7) is a key component of the small ribosomal subunit in the mitochondrion. This family includes RPS7 from Viridiplantae.The ribosome small subunit is one of the two subunits of ribosome organelles that use mRNA as a template for protein synthesis in a process called translation. The small subunits of bacteria and eukaryotes have the same shape of head, body, platform, beak, and shoulder. RPS7 is located at the head of the small subunit. RPS7 is a primary ribosomal RNA (rRNA) binding protein that assists in rRNA folding and the binding of other proteins during small subunit assembly in all species. RPS7 is also involved in the formation of the mRNA exit channel at the interface of the large and small subunits [ , ]. Some ribosomal proteins have extra ribosomal functions in cell differentiation and apoptosis [, ].

Name: Pentatricopeptide repeat-containing protein 2, mitochondrial
Type: Family
Description: Pentatricopeptide repeat (PPR) proteins constitute a large family of RNA-binding proteins that contain a canonical 35 residue repeat motif. Seven examples have been identified in human mitochondria, and are known to affect mitochondrial translation [ , ]. One of these is PTCD2, a pentatricopeptide domain (PTCD)-containing protein that affects mitochondrial translation. PTCD2 appears to have a role in processing RNA transcripts involving cytochrome b encoded by mitochondrial DNA []. Disruption in PTCD2 resulted in elevated levels of the unprocessed precursor encoding cytochrome b. PTCD2 has been identified as a target for autoantibodies in neurodegenerative disease and is used as a biomarker for Alzheimer disease [].
