This domain is found in Inositol polyphosphate 5-phosphatase OCRL from humans and similar eukaryotic proteins. OCRL is an enzyme that dephosphorylate the 5' position of the inositol ring. It is thought to help coordinate intracellular membrane traffic through changes in the phosphoinositide composition of associated membranes. Mutations in this protein are responsible for Lowe syndrome. This entry represents a domain found C-terminal to Pfam:PF03372 and N-terminal to Pfam:PF00620. It is comprised by two layers of beta- sheets and is closely related to the members of the family of immunoglobulin-like beta-sandwiches [1,3].	Domain
