Protein Information (annotations from UniProt)

Database IDHIV0012251
UniProt IDQ14999
Primary gene name(s)CUL7
Synonym gene name(s)KIAA0076
Protein nameCullin-7
Protein functionCore 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, PubMed:24793695. Interaction with CUL9 is required to inhibit CUL9 activity and ubiquitination of BIRC5, PubMed:24793696. 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, PubMed:21572988, PubMed:24362026. Ubiquitination of GORASP1 regulates Golgi morphogenesis and dendrite patterning in brain, PubMed:21572988. 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, PubMed:18498745. The Cul7-RING(FBXW8 complex also mediates ubiquitination of MAP4K1/HPK1: recognizes and binds autophosphorylated MAP4K1/HPK1, leading to its degradatation, thereby affecting cell proliferation and differentiation, PubMed:24362026. Acts as a regulator in trophoblast cell epithelial-mesenchymal transition and placental development, PubMed:20139075. Does not promote polyubiquitination and proteasomal degradation of p53/TP53, PubMed:16547496, PubMed:17332328. 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. {ECO:0000269|PubMed:16547496, ECO:0000269|PubMed:17332328, ECO:0000269|PubMed:18498745, ECO:0000269|PubMed:20139075, ECO:0000269|PubMed:21572988, ECO:0000269|PubMed:24362026, ECO:0000269|PubMed:24793695, ECO:0000269|PubMed:24793696}.
Subcellular locationCytoplasm. 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. {ECO:0000269|PubMed:24793695}.
