MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the serine/threonine protein kinase family. The encoded protein, a component of a cytokine-activated protein complex that is an inhibitor of the essential transcription factor NF-kappa-B complex, phosphorylates sites that trigger the degradation of the inhibitor via the ubiquination pathway, thereby activating the transcription factor. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for targeted null mutations die neonataly and exhibit thickened, taut, adhesive skin that prevents appendages from protruding from the trunk, absence of whiskers, skeletal abnormalities, and closed esophagus. [provided by MGI curators]
