PSCD4 Antibody - N-terminal region : Biotin (ARP54947_P050-Biotin)

PSCD4 promotes guanine-nucleotide exchange on ARF1 and ARF5. PSCD4 promotes the activation of ARF through replacement of GDP with GTP.Pleckstrin homology, Sec7 and coiled/coil domains 4 (PSCD4) 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 (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. The PSCD4 exhibits GEP activity in vitro with both ARF1 and ARF5 but is inactive with ARF6. The PSCD4 and PSCD1 gene structures are very similar.

All conjugated antibodies should be stored in light-protected vials or covered with a light protecting material (i.e. aluminum foil) . Conjugated antibodies are stable for at least 12 months at 4C. If longer storage is desired (24 months), conjugates may be diluted with up to 50% glycerol and stored at -20C to -80C. Freezing and thawing conjugated antibodies will compromise enzyme activity as well as antibody binding.
