Protein Domain : Kelch-like protein 24, BACK domain IPR047071

Type	Domain
Description	The KLHL (Kelch-like) proteins generally have a BTB/POZ domain, a BACK domain, and five to six Kelch motifs. They constitute a subgroup at the intersection between the BTB/POZ domain and Kelch domain superfamilies. The BTB/POZ domain facilitates protein binding [ ], while the Kelch domain (repeats) form β-propellers. The Kelch superfamily of proteins can be subdivided into five groups: (1) N-propeller, C-dimer proteins, (2) N-propeller proteins, (3) propeller proteins, (4) N-dimer, C-propeller proteins, and (5) C-propeller proteins. KLHL family members belong to the N-dimer, C-propeller subclass of Kelch repeat proteins []. In addition to BTB/POZ and Kelch domains, the KLHL family members contain a BACK domain, first described as a 130-residue region of conservation observed amongst BTB-Kelch proteins []. Many of the Kelch-like proteins have been identified as adaptors for the recruitment of substrates to Cul3-based E3 ubiquitin ligases [, ].Kelch-like protein 24 (KLHL24, also known as kainate receptor-interacting protein for GluR6 (KRIP6) or protein DRE1) belongs to the KLHL family [ ]. is necessary to maintain the balance between intermediate filament stability and degradation, a process that is essential for skin integrity. KLHL24 is a component of a BCR (BTB-CUL3-RBX1) E3 ubiquitin ligase complex that mediates ubiquitination of KRT14 and controls its levels during keratinocyte differentiation [ , , , , . KLHL24 binds to and regulates the GluR6a kainate receptor [ ]. It also modulates the interaction of PICK1 with GluR6 kainate receptors [, , ]. Kainate receptors (KAR) are ionotropic receptors that respond to the neurotransmitter glutamate and have been implicated in epilepsy, stroke, Alzheimer's and neuropathic pain [].This entry represents the BACK domain.
