UBE2K

(redirected from Ubiquitin-protein ligase)

UBE2K

A gene on chromosome 4p14 that encodes a ubiquitin-conjugating enzyme which interacts with RING finger proteins. It ubiquitinates huntingtin, a protein linked to Huntington's disease, the known functions of which include a role in aggregate formation of polyglutamine proteins and apoptosis suppression in polyglutamine diseases, as well as a role in releasing newly synthesised MHC class-I heavy chains from the endoplasmic reticulum.

The researchers then compared the gene with that in normal rats to find that only diabetes-afflicted rats showed ''nonsense mutation'' in Cb1b, a kind of ubiquitin-protein ligases, they said in the journal.
