Description: The sequences featured in this family are similar to a region close to the N-terminus of yeast exportin 1 (Xpo1, Crm1, Swiss:P14068). This region is found just C-terminal to an importin-beta N-terminal domain (Pfam:PF03810) in many members of this family. Exportin 1 is a nuclear export receptor that interacts with leucine-rich nuclear export signal (NES) sequences, and Ran-GTP, and is involved in translocation of proteins out of the nucleus [1,2].

Description: This domain is found in a variety of membrane or lipid associated proteins. It is called the PLAT (Polycystin-1, Lipoxygenase, Alpha-Toxin) domain or LH2 (Lipoxygenase homology) domain. The known structure of pancreatic lipase shows this domain binds to procolipase Pfam:PF01114, which mediates membrane association. So it appears possible that this domain mediates membrane attachment via other protein binding partners. The structure of this domain is known for many members of the family and is composed of a beta sandwich.

Description: Subtilases are a family of serine proteases. They appear to have independently and convergently evolved an Asp/Ser/His catalytic triad, like that found in the trypsin serine proteases (see Pfam:PF00089). Structure is an alpha/beta fold containing a 7-stranded parallel beta sheet, order 2314567.
Ontology Term
Description: This family includes the proteinase B inhibitor from Saccharomyces cerevisiae and the activation peptides from peptidases of the subtilisin family. The subtilisin propeptides are known to function as molecular chaperones, assisting in the folding of the mature peptidase [1], but have also been shown to act as 'temporary inhibitors' [2].

Initiation factor 2 binds to Met-tRNA, GTP and the small ribosomal subunit. Members of this family have also been characterised as 5-methylthioribose- 1-phosphate isomerases, an enzyme of the methionine salvage pathway. The crystal structure of Ypr118w, a non-essential, low-copy number gene product from Saccharomyces cerevisiae, reveals a dimeric protein with two domains and a putative active site cleft [2].

Leucine Rich Repeats are short sequence motifs present in a number of proteins with diverse functions and cellular locations. These repeats are usually involved in protein-protein interactions. Each Leucine Rich Repeat is composed of a beta-alpha unit. These units form elongated non-globular structures. Leucine Rich Repeats are often flanked by cysteine rich domains.

Description: This family is structurally different from the alpha/beta hydrolase family (Pfam:PF00561). This family includes L-2-haloacid dehalogenase, epoxide hydrolases and phosphatases. The structure of the family consists of two domains. One is an inserted four helix bundle, which is the least well conserved region of the alignment, between residues 16 and 96 of Swiss:P24069. The rest of the fold is composed of the core alpha/beta domain [1]. Those members with the characteristic DxD triad at the N-terminus are probably phosphatidylglycerolphosphate (PGP) phosphatases involved in cardiolipin biosynthesis in the mitochondria [2].

Description: This domain is found in cation transport ATPases, including phospholipid-transporting ATPases, calcium-transporting ATPases, and sodium-potassium ATPases [1-2].
Ontology Term
Description: This family consists of the DVL family of proteins. In a gain-of-function genetic screen for genes that influence fruit development in Arabidopsis, DEVIL (DVL) gene was identified. DVL is a small protein and overexpression of the protein results in pleiotropic phenotypes featured by shortened stature, rounder rosette leaves, clustered inflorescences, shortened pedicles, and siliques with pronged tips. DVL family is a novel class of small polypeptides and the overexpression phenotypes suggest that these polypeptides may have a role in plant development [1].
Ontology Term
Description: Protein phosphorylation, which plays a key role in most cellular activities, is a reversible process mediated by protein kinases and phosphoprotein phosphatases. Protein kinases catalyse the transfer of the gamma phosphate from nucleotide triphosphates (often ATP) to one or more amino acid residues in a protein substrate side chain, resulting in a conformational change affecting protein function. Phosphoprotein phosphatases catalyse the reverse process. Protein kinases fall into three broad classes, characterised with respect to substrate specificity [1]; Serine/threonine-protein kinases, tyrosine-protein kinases, and dual specificity protein kinases (e.g. MEK - phosphorylates both Thr and Tyr on target proteins). This entry represents the catalytic domain found in a number of serine/threonine- and tyrosine-protein kinases. It does not include the catalytic domain of dual specificity kinases.

The DEAD box helicases are involved in various aspects of RNA metabolism, including nuclear transcription, pre mRNA splicing, ribosome biogenesis, nucleocytoplasmic transport, translation, RNA decay and organellar gene expression.

Description: This domain is named PAZ after the proteins Piwi Argonaut and Zwille. This domain is found in two families of proteins that are involved in post-transcriptional gene silencing. These are the Piwi family and the Dicer family, that includes the Carpel factory protein. The function of the domains is unknown but has been suggested to mediate complex formation between proteins of the Piwi and Dicer families by hetero-dimerisation. The three-dimensional structure of this domain has been solved [2-4]. The PAZ domain is composed of two subdomains. One subdomain is similar to the OB fold, albeit with a different topology. The OB-fold is well known as a single-stranded nucleic acid binding fold. The second subdomain is composed of a beta-hairpin followed by an alpha-helix. The PAZ domains shows low-affinity nucleic acid binding and appears to interact with the 3' ends of single-stranded regions of RNA in the cleft between the two subdomains. PAZ can bind the characteristic two-base 3' overhangs of siRNAs, indicating that although PAZ may not be a primary nucleic acid binding site in Dicer or RISC, it may contribute to the specific and productive incorporation of siRNAs and miRNAs into the RNAi pathway.
Ontology Term
Description: This domain is found in members of the Dicer protein family which function in RNA interference, an evolutionarily conserved mechanism for gene silencing using double-stranded RNA (dsRNA) molecules. It is essential for the activity of Dicer [1,2]. It is a divergent double stranded RNA-binding domain [3]. The N-terminal alpha helix of this domain is in a different orientation to that found in canonical dsRNA-binding domains. This results in a change of charge distribution at the potential dsRNA-binding surface and in the N- and C-termini of the domain being in close proximity [4]. This domain has weak dsRNA-binding activity. It mediates heterodimerisation of Dicer proteins with their respective protein partners [4].

PADRE typically occurs in small single-domain proteins with a bipartite architecture.

This domain is associated with plant defense upon diverse stress stimulus and has a role in disease resistance to fungi [1].

Description: The RRM motif is probably diagnostic of an RNA binding protein. RRMs are found in a variety of RNA binding proteins, including various hnRNP proteins, proteins implicated in regulation of alternative splicing, and protein components of snRNPs. The motif also appears in a few single stranded DNA binding proteins. The RRM structure consists of four strands and two helices arranged in an alpha/beta sandwich, with a third helix present during RNA binding in some cases The C-terminal beta strand (4th strand) and final helix are hard to align and have been omitted in the SEED alignment The LA proteins (Swiss:P05455) have an N terminal rrm which is included in the seed. There is a second region towards the C terminus that has some features characteristic of a rrm but does not appear to have the important structural core of a rrm.

Description: The full-length members of this family, eg Swiss:P53816, are representatives of a novel class II tumour-suppressor family, designated as H-REV107-like. This domain is the catalytic N-terminal proline-rich region of the protein. The downstream region is a putative C-terminal transmembrane domain which is found to be crucial for cellular localisation, but not necessary for the enzyme activity [1]. H-REV107-like proteins are homologous to lecithin retinol acyltransferase (LRAT), an enzyme that catalyses the transfer of the sn-1 acyl group of phosphatidylcholine to all-trans-retinol and forming a retinyl ester [2].
