UBE2K(redirected from Ubiquitin carrier protein)
UBE2KA 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.
