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.
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 (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 degradation, 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.
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 SV40 Large T antigen; this interaction seems to inhibit CUL7. Interacts with OBSL1. Interacts (as part of the 3M complex) with HDAC4 and HDAC5; it is negatively regulated by ANKRA2.
Post-translational Modifications: According to a report, may not be neddylated despite the conserved consensus site for neddylation at Lys-1576.
Similarity: Belongs to the cullin family.

The protein encoded by this gene is a component of an E3 ubiquitin-protein ligase complex. The encoded protein interacts with TP53, CUL9, and FBXW8 proteins. Defects in this gene are a cause of 3M syndrome type 1 (3M1). Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2009]
