FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene is a member of the MAPKKK family of signal transduction molecules and encodes a protein with an N-terminal kinase catalytic domain, followed by a leucine zipper motif and a sterile-alpha motif (SAM). This magnesium-binding protein forms homodimers and is located in the cytoplasm. The protein mediates gamma radiation signaling leading to cell cycle arrest and activity of this protein plays a role in cell cycle checkpoint regulation in cells. The protein also has pro-apoptotic activity. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit complete lethality at E9.5 with growth retardation. Mice homozygous for an allele lacking the SAM domain exhibit low penetrant unilateral complex hindlimb duplication phenotype. [provided by MGI curators]
