Q14999 CUL7_HUMAN:

Highly expressed in fetal kidney and adult skeletal muscle. Also abundant in fetal brain, as well as in adult pancreas, kidney, placenta and heart. Detected in trophoblasts, lymphoblasts, osteoblasts, chondrocytes and skin fibroblasts.

Description:
Component of a probable SCF-like E3 ubiquitin-protein ligase complex, which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Probably plays a role in the degradation of proteins involved in endothelial proliferation and/or differentiation (By similarity). Seems not to promote polyubiquitination and proteasomal degradation of TP53. In vitro, complexes of CUL7 with either CUL9 or FBXW8 or TP53 contain E3 ubiquitin-protein ligase activity.

Research Backgrounds

Function:

Core component of the 3M and Cul7-RING(FBXW8) complexes, which mediates the ubiquitination of target proteins. Core component of the 3M complex, a complex required to regulate microtubule dynamics and genome integrity. It is unclear how the 3M complex regulates microtubules, it could act by controlling the level of a microtubule stabilizer. Interaction with CUL9 is required to inhibit CUL9 activity and ubiquitination of BIRC5. Core component of a Cul7-RING ubiquitin-protein ligase with FBXW8, which mediates ubiquitination and consequent degradation of target proteins such as GORASP1, IRS1 and MAP4K1/HPK1. Ubiquitination of GORASP1 regulates Golgi morphogenesis and dendrite patterning in brain. Mediates ubiquitination and degradation of IRS1 in a mTOR-dependent manner: the Cul7-RING(FBXW8) complex recognizes and binds IRS1 previously phosphorylated by S6 kinase (RPS6KB1 or RPS6KB2). The Cul7-RING(FBXW8) complex also mediates ubiquitination of MAP4K1/HPK1: recognizes and binds autophosphorylated MAP4K1/HPK1, leading to its degradation, thereby affecting cell proliferation and differentiation. Acts as a regulator in trophoblast cell epithelial-mesenchymal transition and placental development. Does not promote polyubiquitination and proteasomal degradation of p53/TP53. While the Cul7-RING(FBXW8) and the 3M complexes are associated and involved in common processes, CUL7 and the Cul7-RING(FBXW8) complex may be have additional functions.

PTMs:

According to a report, may not be neddylated despite the conserved consensus site for neddylation at Lys-1576.

Subcellular Location:

Cytoplasm. Cytoplasm>Cytoskeleton>Microtubule organizing center>Centrosome. Cytoplasm>Perinuclear region. Golgi apparatus.
Note: Colocalizes with FBXW8 at the Golgi apparatus in neurons; localization to Golgi is mediated by OBSL1. During mitosis, localizes to the mitotic apparatus (PubMed:24793695). CCDC8 is required for centrosomal location (PubMed:24793695).

Tissue Specificity:

Highly expressed in fetal kidney and adult skeletal muscle. Also abundant in fetal brain, as well as in adult pancreas, kidney, placenta and heart. Detected in trophoblasts, lymphoblasts, osteoblasts, chondrocytes and skin fibroblasts.

Subunit Structure:

Component of the 3M complex, composed of core components CUL7, CCDC8 and OBSL1. Part of a Cul7-RING complex consisting of CUL7, RBX1, SKP1 and FBXW8. Interacts with a complex of SKP1 and FBXW8, but not with SKP1 alone. Interacts with CUL9; leading to inhibit CUL9 activity. Interacts with FBXW8; interaction is mutually exclusive of binding to CUL9 or p53/TP53. Interacts with p53/TP53; the interaction preferentially involves tetrameric and dimeric p53/TP53. The CUL7-CUL9 heterodimer seems to interact specifically with p53/TP53. Interacts with CUL1; the interactions seems to be mediated by FBXW8. Interacts with OBSL1. Interacts (as part of the 3M complex) with HDAC4 and HDAC5; it is negatively regulated by ANKRA2.

(Microbial infection) Interacts with SV40 Large T antigen; this interaction seems to inhibit CUL7.

Family&Domains:

Belongs to the cullin family.
