Ubiquitin-conjugating enzyme E2 variant 1 is a protein that in humans is encoded by the UBE2V1 gene.Ubiquitin-conjugating E2 enzyme variant proteins constitute a distinct subfamily within the E2 protein family. They have sequence similarity to other ubiquitin-conjugating enzymes but lack the conserved cysteine residue that is critical for the catalytic activity of E2s.
