Arf-GAP with SH3 domain, ANK repeat and PH domain-containing protein 1 (Asap1)

May function as a signal transduction protein involved in the differentiation of fibroblasts into adipocytes and possibly other cell types. Plays a role in ciliogenesis (By similarity).

Posseses phosphatidylinositol 4,5-bisphosphate-dependent GTPase- activating protein activity for ARF1 (ADP ribosylation factor 1) and ARF5 and a lesser action towards ARF6. May coordinate membrane trafficking with cell growth or actin cytoskeleton remodeling by binding to both SRC and PIP2.
