Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0003802
UniProt IDQ9ULH1
Primary gene name(s)ASAP1
Synonym gene name(s)DDEF1, KIAA1249
Protein nameArf-GAP with SH3 domain, ANK repeat and PH domain-containing protein 1
Protein functionPossesses phosphatidylinositol 4,5-bisphosphate-dependent GTPase-activating protein activity for ARF1, ADP ribosylation factor 1 and ARF5 and a lesser activity towards ARF6. May coordinate membrane trafficking with cell growth or actin cytoskeleton remodeling by binding to both SRC and PIP2. May function as a signal transduction protein involved in the differentiation of fibroblasts into adipocytes and possibly other cell types, By similarity. Plays a role in ciliogenesis. {ECO:0000250, ECO:0000269|PubMed:20393563}.
Subcellular locationCytoplasm {ECO:0000250}. Membrane {ECO:0000250}. Note=Predominantly cytoplasmic. Partially membrane-associated. {ECO:0000250}.
