Ubiquitin-conjugating enzyme E2 variant 1, also known as Kua-UEV, is a human gene. [3]
The Kua-UEV mRNA is an infrequent but naturally occurring co-transcribed product of the neighboring Kua and UBE2V1 genes. [4] 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. Two alternative transcripts encoding different isoforms have been described. The proteins produced by these transcripts have UEV1 B domains but the proteins are localized to the cytoplasm rather than to the nucleus. The significance of these co-transcribed mRNAs and the function of their protein products have not yet been determined. [3]
Ubiquitin is a small regulatory protein found in most tissues of eukaryotic organisms, i.e., it is found ubiquitously. It was discovered in 1975 by Gideon Goldstein and further characterized throughout the late 1970s and 1980s. Four genes in the human genome code for ubiquitin: UBB, UBC, UBA52 and RPS27A.
60S ribosomal protein L40 (RPL40) is a protein that in humans is encoded by the UBA52 gene.
CDC34 is a gene that in humans encodes the protein Ubiquitin-conjugating enzyme E2 R1. This protein is a member of the ubiquitin-conjugating enzyme family, which catalyzes the covalent attachment of ubiquitin to other proteins.
Ubiquitin-conjugating enzyme E2 N is a protein that in humans is encoded by the UBE2N gene.
Ubiquitin-conjugating enzyme E2 D3 is a protein that in humans is encoded by the UBE2D3 gene.
Ubiquitin-conjugating enzyme E2 G2 is a protein that in humans is encoded by the UBE2G2 gene.
Ubiquitin-conjugating enzyme E2 variant 2 is a protein that in humans is encoded by the UBE2V2 gene. Ubiquitin-conjugating enzyme E2 variant proteins constitute a distinct subfamily within the E2 protein family.
