RCBTB2 (RCC1 and BTB domain-containing protein 2), also known as RCC1L2 or KIAA0206. is a multifunctional protein encoded by the RCBTB2 gene in humans. Structurally, it contains two conserved domains: an N-terminal RCC1 (Regulator of Chromosome Condensation 1) domain and a C-terminal BTB/POZ (Broad-Complex, Tramtrack, and Bric-à-brac/Poxvirus and Zinc Finger) domain. The RCC1 domain, typically involved in nucleotide exchange for Ran GTPase, suggests a role in regulating nucleocytoplasmic transport, mitosis, or chromatin interactions. The BTB/POZ domain, commonly associated with protein-protein interactions and scaffolding in ubiquitin ligase complexes, hints at potential involvement in protein degradation pathways or transcriptional regulation.
Functionally, RCBTB2 is implicated in diverse cellular processes, including cell cycle control, DNA damage response, and oxidative stress management. Studies link it to maintaining genomic stability, possibly by interacting with DNA repair machinery or modulating checkpoint signaling. Its expression is tissue-specific, with higher levels observed in the brain, liver, and testes. Dysregulation of RCBTB2 has been associated with pathological conditions, particularly cancer. It may act as a tumor suppressor or oncogene depending on context, with reported deletions in ovarian and breast cancers, while overexpression correlates with poor prognosis in hepatocellular carcinoma.
Recombinant RCBTB2 protein is engineered for in vitro studies, often produced using bacterial or mammalian expression systems with affinity tags (e.g., His-tag) for purification. This tool enables exploration of its biochemical properties, interactome mapping, and structural analysis (e.g., crystallography). Researchers utilize it to investigate its role in cancer progression, cellular stress responses, and potential therapeutic targeting. Recent evidence also connects RCBTB2 variants to inherited retinal degeneration, expanding its biomedical relevance beyond oncology. Despite progress, its precise molecular mechanisms remain partially characterized, driving ongoing research into its dual-domain coordination and context-dependent functions.
