Inositol polyphosphate 5-phosphatase OCRL-1, also known as Lowe oculocerebrorenal syndrome protein, is an enzyme encoded by the OCRL gene located on the X chromosome in humans.^[5]

This gene encodes a phosphatase enzyme involved in actin polymerization, and is found in the trans-Golgi network.^[5]

Mutation in this gene are associated with oculocerebrorenal syndrome^[6] and also with Dent's disease.^[7]^[8]
