MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that belongs to the inositol phosphokinase (IPK) family. This protein is likely responsible for the conversion of inositol hexakisphosphate (InsP6) to diphosphoinositol pentakisphosphate (InsP7/PP-InsP5). It may also convert 1,3,4,5,6-pentakisphosphate (InsP5) to PP-InsP4 and affect the growth suppressive and apoptotic activities of interferon-beta in some ovarian cancers. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a null allele are resistant to radiation-induced mortality and show increased double-strand DNA break repair and incidence of induced aerodigestive tract carcinomas. Homozygotes for another null allele show increased B cell viability after radiation or neocarzinostatin treatment. [provided by MGI curators]
