MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Phosphatidylinositolpolyphosphates (PtdInsPs) are centrally involved in many biologic processes, ranging from cell growth and organization of the actin cytoskeleton to endo- and exocytosis. PI4KII phosphorylates PtdIns at the D-4 position, an essential step in the biosynthesis of PtdInsPs (Barylko et al., 2001 [PubMed 11244087]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Mice homozygous for a gene trap allele develop a progressive neurologic disease typified by urinary incontinence, tremor, limb weakness, weight loss, cerebellar gliosis, Purkinje cell loss, degeneration of spinal cord axons and premature death. Mutant males are sterile while females are subfertile. [provided by MGI curators]
