Description
ASAP1 Polyclonal Antibody. ASAP1, also known as Development and differentiation enhancing factor 1, is a protein with two ANK repeats, an Arf-GAP domain, a PH domain and a SH3 domain. ASAP1 is a homodimer known to interact with SRC and CRK and its activity is stimulated by phosphatidylinositol 4,5-biphosphate (PIP2). It possesses phosphatidylinositol 4,5-biphosphate-dependent GTPase-activating protein activity for ARF1 (ADP ribosylation factor 1) and ARF5 and a lesser activity towards ARF6. It may coordinate membrane trafficking with cell growth or actin cytoskeleton remodeling by binding to both SRC and PIP2 and may also function as a signal transduction protein involved in the differentiation of fibroblasts into adipocytes and possibly ot
