Phosphatase that specifically hydrolyzes the 5-phosphate of inositol 1,4,5-trisphosphate to inositol 1,4-bisphosphate, and inositol 1,3,4,5-tetrasphosphate to inositol 1,3,4-trisphosphate ( ). Plays a crucial role in the survival of cerebellar Purkinje cells (By similarity).
Subcellular locations: Cell membrane, Cell projection, Dendrite
Predominantly expressed in heart, brain, and skeletal muscle . In brain; high level in Purkinje cells .
