C9orf100. also known as recombinant human Vav-like protein, is a poorly characterized protein encoded by the C9orf100 gene located on chromosome 9 (9p13.3). It belongs to the Vav family of proteins, which function as guanine nucleotide exchange factors (GEFs) for Rho/Rac GTPases, playing roles in intracellular signaling pathways. While Vav family members (Vav1-3) are well-studied in immune regulation, cytoskeletal reorganization, and oncogenesis, C9orf100 remains under-researched. Structurally, it shares homology with Vav proteins, containing conserved domains such as a Dbl-homology (DH) domain critical for GEF activity and a pleckstrin homology (PH) domain involved in membrane interactions. However, unlike canonical Vav proteins, C9orf100 lacks the N-terminal calponin homology (CH) and acidic (AC) domains, suggesting functional divergence.
Recombinant C9orf100 is typically produced in expression systems (e.g., E. coli, HEK293) for in vitro studies to elucidate its biochemical properties and interactions. Preliminary studies hint at its potential involvement in cellular processes like cell adhesion, differentiation, or receptor signaling, but mechanistic details remain unclear. Its dysregulation has been tentatively linked to cancers and neurological disorders, though evidence is limited. Current research focuses on characterizing its GEF specificity, signaling partners, and physiological relevance, aiming to bridge gaps in understanding its role compared to other Vav family members. The protein’s obscurity underscores both its potential as a novel signaling node and the need for systematic functional studies.
