This gene encodes a member of the PSCD (pleckstrin homology, Sec7 and coiled-coil domains) family. PSCD family members have identical structural organization that consists of an N-terminal coiled-coil motif, a central Sec7 domain, and a C-terminal pleckstrin homology (PH) domain. The coiled-coil motif is involved in homodimerization, the Sec7 domain contains guanine-nucleotide exchange protein (GEP) activity, and the PH domain interacts with phospholipids and is responsible for association of PSCDs with membranes. Members of this family appear to mediate the regulation of protein sorting and membrane trafficking. This encoded protein is involved in the control of Golgi structure and function, and it may have a physiological role in regulating ADP-ribosylation factor protein 6 (ARF) functions, in addition to acting on ARF1.

GeneCards Summary for CYTH3 Gene
CYTH3 (Cytohesin 3) is a Protein Coding gene. Among its related pathways are Arf6 signaling events and Golgi-to-ER retrograde transport. GO annotations related to this gene include phosphatidylinositol-3,4,5-trisphosphate binding and ARF guanyl-nucleotide exchange factor activity. An important paralog of this gene is CYTH1.
UniProtKB/Swiss-Prot for CYTH3 Gene
Promotes guanine-nucleotide exchange on ARF1 and ARF6. Promotes the activation of ARF factors through replacement of GDP with GTP.
