Function Converts phosphatidylinositol 3,4,5-trisphosphate (PtdIns 3,4,5-P3) to PtdIns-P2. Specific for lipid substrates, inactive towards water soluble inositol phosphates. {ECO:0000269PubMed:10764818}.
Subcellular Localization Cytoplasm, cytoskeleton, cilium axoneme {ECO:0000269PubMed:19668215, ECO:0000269PubMed:19668216}. Golgi apparatus, Golgi stack membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Note=Peripheral membrane protein associated with Golgi stacks. {ECO:0000250}.
Disease Associations Joubert syndrome 1 (JBTS1) [MIM:213300]: A disorder presenting with cerebellar ataxia, oculomotor apraxia, hypotonia, neonatal breathing abnormalities and psychomotor delay. Neuroradiologically, it is characterized by cerebellar vermian hypoplasia/aplasia, thickened and reoriented superior cerebellar peduncles, and an abnormally large interpeduncular fossa, giving the appearance of a molar tooth on transaxial slices (molar tooth sign). Additional variable features include retinal dystrophy and renal disease. {ECO:0000269PubMed:19668216}. Note=The disease is caused by mutations affecting the gene represented in this entry.Mental retardation, truncal obesity, retinal dystrophy, and micropenis (MORMS) [MIM:610156]: An autosomal recessive disorder characterized by moderate mental retardation, truncal obesity, congenital non-progressive retinal dystrophy, and micropenis in males. The phenotype is similar to Bardet-Biedl syndrome and Cohen syndrome Distinguishing features are the age of onset, the non-progressive nature of the visual impairment, lack of dysmorphic facies, skin or gingival infection, microcephaly, mottled retina, polydactyly, and testicular anomalies. {ECO:0000269PubMed:19668215}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Detected in brain, heart, pancreas, testis and spleen. {ECO:0000269PubMed:10764818}.
