General annotation (Comments)

Function	Plays a role in membrane ruffling and assembly of clathrin-coated pits at the synapse. Mediates RAC1-dependent reorganization of actin filaments By similarity. Participates in the biosynthesis of phosphatidylinositol-4,5-bisphosphate.
Catalytic activity	ATP + 1-phosphatidyl-1D-myo-inositol 4-phosphate = ADP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate.
Enzyme regulation	Activated by interaction with TLN2.
Subunit structure	Interacts with TLN1 and CSK By similarity. Interacts with TLN2 and ARF6.
Subcellular location	Cell membrane; Peripheral membrane protein; Cytoplasmic side. Note: Cytoplasmic, associated with the plasma membrane. Detected in focal adhesion plaques, membrane ruffles and plasma membrane invaginations. Ref.3 Ref.4 Ref.5
Involvement in disease	Defects in PIP5K1C are the cause of lethal congenital contractural syndrome type 3 (LCCS3) [MIM:611369]; also known as multiple contractural syndrome Israeli Bedouin type B. LCCS is an autosomal recessive disorder characterized by early fetal hydrops and akinesia, the Pena-Shokeir phenotype, specific neuropathology with degeneration of anterior horn neurons and extreme skeletal muscle atrophy. LCCS3 patients present at birth with severe multiple joint contractures with severe muscle wasting and atrophy, mainly in the legs. LCCS3 can be distinguished from the original LCCS by the absence of hydrops, fractures, and multiple pterygia. Ref.6
Sequence similarities	Contains 1 PI5K domain.
