This gene encodes an inositol polyphosphate 5-phosphatase. The responsible gene locus is at Xq26.1. This phosphatase enzyme is in part responsible for regulating membrane trafficking actin polymerization, and is located in several subcellular parts of the trans-Golgi network.

Deficiencies in OCRL-1 are associated with oculocerebrorenal syndrome^[6] and also have been linked to Dent's disease.^[7][8]
