CCNB1IP1 (Cyclin B1 Interacting Protein 1), also known as E3 ubiquitin-protein ligase, is a critical component of the ubiquitin-proteasome system that regulates protein degradation and cellular homeostasis. It functions as an E3 ligase, catalyzing the transfer of ubiquitin molecules to specific substrate proteins, marking them for proteasomal degradation or functional modulation. CCNB1IP1 is best characterized for its role in cell cycle regulation, particularly during the G2/M phase transition. It interacts with Cyclin B1. a key regulator of mitosis, and contributes to the maintenance of genomic stability by mediating homologous recombination repair during meiosis and mitosis. Studies suggest its involvement in DNA damage response pathways, where it facilitates the ubiquitination of repair-associated proteins, such as RAD51. to ensure proper DNA recombination and error correction.
Altered expression or mutations in CCNB1IP1 have been linked to various diseases, including cancer and infertility. For instance, its dysregulation may disrupt cell cycle checkpoints, promote genomic instability, or impair gametogenesis. In cancer, CCNB1IP1 has been implicated as both a tumor suppressor and an oncogene, depending on context, highlighting its complex regulatory roles. Recombinant human CCNB1IP1 is widely used in biochemical assays to study enzyme-substrate interactions, ubiquitination mechanisms, and potential therapeutic targeting. Its structural features, including conserved RING and SPRY domains, enable substrate recognition and functional versatility in cellular processes. Ongoing research aims to elucidate its diverse physiological and pathological functions for biomedical applications.
