Ubiquitin-conjugating enzyme E2 K is a protein that in humans is encoded by the UBE2K gene.^[5]^[6]^[7]

The protein encoded by this gene belongs to the ubiquitin-conjugating enzyme family. It binds selectively to a large region at the N terminus of huntingtin. This interaction is not influenced by the length of the huntingtin polyglutamine tract. This protein has been implicated in the degradation of huntingtin and suppression of apoptosis.^[7]

Interactions

HIP2 has been shown to interact with Huntingtin^[5]^[8] and RNF2.^[9]
