Protein Structure

UniProt Annotation

Function

Binds specifically to phosphatidylinositol 3,4- diphosphate (PtdIns3,4P2), but not to other phosphoinositides. May recruit other proteins to the plasma membrane. {ECO:0000269PubMed:11001876, ECO:0000269PubMed:11513726, ECO:0000269PubMed:14516276}.

Subcellular Localization

Cytoplasm. Cell membrane; Peripheral membrane protein. Nucleus. Note=Locates to the plasma membrane after treatments that stimulate the production of PtdIns3,4P2.

Disease Associations

Tissue Specificity

Highly expressed in skeletal muscle, thymus, pancreas, placenta and lung. Detected at low levels in brain, heart, peripheral blood leukocytes, testis, ovary, spinal cord, thyroid, kidney, liver, small intestine and colon. {ECO:0000269PubMed:11001876, ECO:0000269PubMed:12101241}.
