  • 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.
  • Tissue specificity

    Detected in brain, heart, pancreas, testis and spleen.
  • Involvement in disease

    Defects in INPP5E are the cause of Joubert syndrome type 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.
    Defects in INPP5E are the cause of mental retardation-truncal obesity-retinal dystrophy-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.
  • Sequence similarities

    Belongs to the inositol 1,4,5-trisphosphate 5-phosphatase type IV family.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

    Cytoplasm > cytoskeleton > cilium axoneme. Golgi apparatus > Golgi stack membrane. Peripheral membrane protein associated with Golgi stacks.
