This gene encodes a member of the PSCD family of proteins, which have 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 function as GEPs for ADP-ribosylation factors (ARFs), which are guanine nucleotide-binding proteins involved in vesicular trafficking pathways. This protein exhibits GEP activity in vitro with ARF1 and ARF5, but is inactive with ARF6. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2015]
GeneCards Summary for CYTH4 Gene
CYTH4 (Cytohesin 4) is a Protein Coding gene. Among its related pathways are Golgi-to-ER retrograde transport and Vesicle-mediated transport. GO annotations related to this gene include lipid binding and ARF guanyl-nucleotide exchange factor activity. An important paralog of this gene is CYTH3.
UniProtKB/Swiss-Prot for CYTH4 Gene
Promotes guanine-nucleotide exchange on ARF1 and ARF5. Promotes the activation of ARF factors through replacement of GDP with GTP.
