Protein Structure

UniProt Annotation

Function

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 activity towards ARF6. May coordinate membrane trafficking with cell growth or actin cytoskeleton remodeling by binding to both SRC and PIP2. {ECO:0000250}.

Subcellular Localization

Cytoplasm. Membrane. Note=Predominantly cytoplasmic. Partially membrane-associated.

Disease Associations

Tissue Specificity

Expressed in all tissues examined but a most abundant expression was found in the testis, brain, lung and spleen. A heightened expression was seen in the adipose tissue from obese (ob) and diabetic (db) animals. {ECO:0000269PubMed:10022919}.
