FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The N-end rule pathway is one proteolytic pathway of the ubiquitin system. The recognition component of this pathway, encoded by this gene, binds to a destabilizing N-terminal residue of a substrate protein and participates in the formation of a substrate-linked multiubiquitin chain. This leads to the eventual degradation of the substrate protein. The protein described in this record has a RING-type zinc finger and a UBR-type zinc finger. Mutations in this gene have been associated with Johanson-Blizzard syndrome. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mutants have 20% lower body weight and reduced muscle and adipose tissue. Skeletal muscle lacks a mechanism for targeting proteins for rapid catabolism. Aberrant regulation of fatty acid synthase upon starvation is also observed. [provided by MGI curators]
