PICALM (Phosphatidylinositol Binding Clathrin Assembly Protein) is a Protein Coding gene. Diseases associated with PICALM include Leukemia, Acute Myeloid and Precursor T-Cell Acute Lymphoblastic Leukemia. Among its related pathways are Clathrin derived vesicle budding and Clathrin-mediated endocytosis. PICALM encodes a clathrin assembly protein, which recruits clathrin and adaptor protein complex 2 (AP2) to cell membranes at sites of coated-pit formation and clathrin-vesicle assembly. The protein may be required to determine the amount of membrane to be recycled, possibly by regulating the size of the clathrin cage. The protein is involved in AP2-dependent clathrin-mediated endocytosis at the neuromuscular junction.
