General annotation (Comments)

Function	Converts phosphatidylinositol 4,5-bisphosphate to phosphatidylinositol 4-phosphate. Also converts inositol 1,4,5-trisphosphate to inositol 1,4-bisphosphate and inositol 1,3,4,5-tetrakisphosphate to inositol 1,3,4-trisphosphate. May function in lysosomal membrane trafficking by regulating the specific pool of phosphatidylinositol 4,5-bisphosphate that is associated with lysosomes. Involved in primary cilia assembly. Ref.14 Ref.15
Catalytic activity	1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H2O = 1-phosphatidyl-1D-myo-inositol 4-phosphate + phosphate.
Subunit structure	Interacts with APPL1, FAM109A/SES1 and FAM109B/SES2; APPL1-binding and FAM109A-binding are mutually exclusive. Interacts with clathrin heavy chain. Interacts with several Rab GTPases, at least RAB1B, RAB5A, RAB6A, RAB8A and RAB31; these interactions may play a dual role in targeting OCRL to the specific membranes and stimulating the phosphatase activity. Interaction with RAB8A modulates OCRL recruitment to cilia. Ref.11 Ref.13 Ref.14 Ref.17 Ref.19
Subcellular location	Cytoplasmic vesicle › phagosome membrane By similarity. Early endosome membrane. Membrane › clathrin-coated pit. Cell projection › cilium › photoreceptor outer segment. Cytoplasmic vesicle By similarity. Endosome By similarity. Golgi apparatus › trans-Golgi network By similarity. Note: Also found on macropinosomes. Ref.11 Ref.14 Ref.17 Ref.19
Tissue specificity	Brain, skeletal muscle, heart, kidney, lung, placenta and fibroblasts. Expressed in the retina and the retinal pigment epithelium. Ref.14
Domain	The ASH (ASPM-SPD2-Hydin) and RhoGAP (Rho GTPase activating) domains form a single folding module. The ASH domain has an immunoglobulin-like fold, the Rho-GAP domain lacks the catalytic arginine and is catalytically inactive. The ASH-RhoGAP module regulates the majority of the protein-protein interactions currently described. The ASH domain mediates association with membrane-targeting Rab GTPases. The Rho-GAP domain interacts with the endocytic adapter APPL1, which is then displaced by FAM109A and FAM109B as endosomes mature. Ref.17
Involvement in disease	Lowe oculocerebrorenal syndrome (OCRL) [MIM:309000]: X-linked multisystem disorder affecting eyes, nervous system, and kidney. It is characterized by hydrophthalmia, cataract, mental retardation, vitamin D-resistant rickets, aminoaciduria, and reduced ammonia production by the kidney. Ocular abnormalities include cataract, glaucoma, microphthalmos, and decreased visual acuity. Developmental delay, hypotonia, behavior abnormalities, and areflexia are also present. Renal tubular involvement is characterized by impaired reabsorption of bicarbonate, amino acids, and phosphate. Musculoskeletal abnormalities such as joint hypermobility, dislocated hips, and fractures may develop as consequences of renal tubular acidosis and hypophosphatemia. Cataract is the only significant manifestation in carriers and is detected by slit-lamp examination. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.11 Ref.13 Ref.21 Ref.22 Ref.23 Ref.24 Ref.25 Ref.26 Ref.29 Ref.30 Dent disease 2 (DD2) [MIM:300555]: A renal disease belonging to the 'Dent disease complex', a group of disorders characterized by proximal renal tubular defect, hypercalciuria, nephrocalcinosis, and renal insufficiency. The spectrum of phenotypic features is remarkably similar in the various disorders, except for differences in the severity of bone deformities and renal impairment. Characteristic abnormalities include low-molecular-weight proteinuria and other features of Fanconi syndrome, such as glycosuria, aminoaciduria, and phosphaturia, but typically do not include proximal renal tubular acidosis. Progressive renal failure is common, as are nephrocalcinosis and kidney stones. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.27 Ref.28 Ref.30
Sequence similarities	Belongs to the inositol 1,4,5-trisphosphate 5-phosphatase type II family. Contains 1 PH domain. Contains 1 Rho-GAP domain.
Caution	It is uncertain whether Met-1, Met-18 or Met-20 is the initiator.
Sequence caution	The sequence AAA59964.2 differs from that shown. Reason: Erroneous initiation.
