PPS — Brachypodium distachyon

Summary

BRADI_5G10117V3 (PPS, also known as BdPPS, BdCIPK07, BdC3H59, BdPT21, BdWD40-33, BdCCS52A) on chromosome 5 of Brachypodium distachyon encodes a thiol-dependent deubiquitinase (EC 3.4.19.12) belonging to the peptidase C19 family. The gene is associated with deubiquitination, proteolysis, regulation of protein stability, the MAPK cascade, protein phosphorylation, and signal transduction, and its product localizes to the cytosol and nucleus. PPS is associated with flowering time, leaf and meristem development, panicle and inflorescence architecture, endosperm traits, gibberellin biosynthesis, ABA signaling, and UV-B response. Related genes in other species link the family to cell cycle, cell division, cell elongation, seed size, grain, seedling, and reproductive development, as well as stem thickness, seed germination, and flavonoid traits.
