The protein encoded by this gene is a member of the PSCD family. Members of this family 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 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 gene is highly expressed in natural killer and peripheral T cells, and regulates the adhesiveness of integrins at the plasma membrane of lymphocytes. A pseudogene of this gene has been defined on the X chromosome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]
GeneCards Summary for CYTH1 Gene
CYTH1 (Cytohesin 1) is a Protein Coding gene. Among its related pathways are Vesicle-mediated transport and Golgi-to-ER retrograde 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 CYTH1 Gene
Promotes guanine-nucleotide exchange on ARF1 and ARF5. Promotes the activation of ARF factors through replacement of GDP with GTP.
