From NCBI Gene:
This gene encodes a protein with 5-phosphatase activity toward polyphosphate inositol. The protein localizes to the cytosol in regions lacking actin stress fibers. It is thought that this protein may negatively regulate the actin cytoskeleton. Alternatively spliced transcript variants encoding different isoforms have been identified.

Inositol 5-phosphatase which acts on inositol 1,4,5-trisphosphate, inositol 1,3,4,5-tetrakisphosphate, phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol 3,4,5-trisphosphate. Has 6-fold higher affinity for phosphatidylinositol 4,5-bisphosphate than for inositol 1,4,5-trisphosphate (PubMed:10753883). Negatively regulates assembly of the actin cytoskeleton. Controls insulin-dependent glucose uptake among inositol 3,4,5-trisphosphate phosphatases; therefore, is the specific regulator for insulin signaling in skeletal muscle (By similarity).

- Muscular dystrophy, congenital, with cataracts and intellectual disability
Muscular dystrophy, congenital, with cataracts and intellectual disability (MDCCAID): An autosomal recessive form of muscular dystrophy with onset in early childhood and characterized by progressive muscle weakness. Almost all patients also have early-onset cataracts and intellectual disability of varying severity. Some patients have seizures. [MIM:617404]
