UBC5B — Capsicum annuum

Summary

T459_18409 (UBC5B) on pepper chromosome 6 encodes a ubiquitin-conjugating enzyme E2-17 kDa, possessing ubiquitin conjugating enzyme activity, ubiquitin-protein transferase activity, and ATP binding. This gene is associated with protein ubiquitination, polyubiquitination, and ubiquitin-dependent proteolysis via the proteasomal pathway, as well as autophagy, programmed cell death, and cell death. It is linked to fruit development, dehiscence, DNA repair, and virus-induced post-transcriptional gene silencing. The encoded protein localises to the nucleus. Associations with cytoplasmic male sterility and germination rate have been noted. Studies of related genes in other species link this family to ubiquitin-protein ligase activity (EC 2.3.2.23).
