Invitrogen™ Human ASAP1 (aa 957-1078) Control Fragment Recombinant Protein

Description

Highest antigen sequence indentity to the following orthologs: Mouse (93%), Rat (93%). This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-61770 (PA5-61770. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

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 other cell types. It is widely expressed in most of the tissues. ASAP1 is a protooncogene involved in invasive breast cancer and in other types of invasive and malignant tumors, such as uveal melanomas.
