Gene Snapshot
Oculocerebrorenal syndrome of Lowe (Ocrl) encodes an inositol polyphosphate 5-phosphatase that regulates PtdIns(4,5)P2 homeostasis by dephosphorylating PtdIns(4,5)P2 on endocytic compartments. In vitro experiments also suggest a role of the product of Ocrl during cytokinesis. [Date last reviewed: 2019-03-14]

Summaries
Gene Group (FlyBase)
PHOSPHATIDYLINOSITOL PHOSPHATE AND INOSITOL PHOSPHATE PHOSPHATASES -
Phosphoinositide phosphate (PtdInsP) phosphatases and Inositol phosphate (InsP) phosphatases are enzymes that catalyze the hydrolysis of phosphate groups from inositol. Many of these phosphatases can act on both PtdInsP and InsP substrates. (Adapted from PMID:23681533).
RHO GTPASE ACTIVATING PROTEINS -
RhoGAPs are GTPase activating proteins for Rho family GTPases. (Adapted from PMID:15731001 and FBrf0158741).

dsRNA made from templates generated with primers directed against CG3573 that is transfected into S2 treated with Listeria monocytogenes reveals CG3573 to be involved in Listeria monocytogenes entry, intracellular growth, and vacuolar escape. Treatment with Sbf dsRNA leads to an approximate 50% decrease in bacterial entry, and an approximate 35% decrease in vacuolar escape.

One of 42 Drosophila genes identified as being most likely to reveal molecular and cellular mechanisms of nervous system development or plasticity relevant to human Mental Retardation disorders.

dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
