Cullin 7 (CUL7) is a member of the Cullin family of scaffold proteins, which play critical roles in ubiquitination by serving as platforms for E3 ubiquitin ligase complexes. These complexes target specific substrates for proteasomal degradation, regulating diverse cellular processes. Human CUL7. encoded by the *CUL7* gene, consists of a canonical Cullin homology domain at its N-terminus and a unique C-terminal region containing binding sites for adaptor proteins like SKP1. ROC1 (RBX1), and the tumor suppressor p53. Unlike other Cullins, CUL7 features a distinct DOC domain that interacts with the ovarian tumor domain-containing protein DOC1/CSN8. contributing to complex assembly and substrate recognition.
Recombinant human CUL7 protein is produced via genetic engineering in systems like bacteria, insect, or mammalian cells, enabling functional studies. It is essential for investigating CUL7’s role in development and disease. Mutations in *CUL7* are linked to 3-M syndrome, a rare autosomal recessive disorder characterized by severe growth retardation, skeletal abnormalities, and distinctive facial features. CUL7 also interacts with the E6-associated protein (E6AP) in certain viruses, implicating it in oncogenic pathways and tumor suppression. Recombinant CUL7 aids in elucidating its structural dynamics, substrate specificity, and regulatory mechanisms, offering potential insights into therapeutic strategies for related genetic disorders or cancers. Its study further clarifies the complexity of ubiquitin-proteasome system regulation in cellular homeostasis.
