Bio Background |
The protein encoded by this gene is a member of the PSCDfamily. Members of this family have identical structuralorganization that consists of an N-terminal coiled-coil motif, acentral Sec7 domain, and a C-terminal pleckstrin homology (PH)domain. The coiled-coil motif is involved in homodimerization, theSec7 domain contains guanine-nucleotide exchange protein (GEP)activity, and the PH domain interacts with phospholipids and isresponsible for association of PSCDs with membranes. Members ofthis family appear to mediate the regulation of protein sorting andmembrane trafficking. The encoded protein exhibits GEP activity invitro with ARF1, ARF3, and ARF6 and is 83% homologous to CYTH1. Twotranscript variants encoding different isoforms have been found forthis gene. |
