PP2A — Brassica juncea

Summary

BJUA03G07870S (PP2A) in Indian mustard (Brassica juncea) chromosome A03 encodes a protein with a PPA2-like domain, a serine/threonine-specific protein phosphatase domain, a calcineurin-like phosphoesterase domain, and a metallo-dependent phosphatase fold, possessing protein serine/threonine phosphatase activity and metal binding. The gene is associated with brassinosteroid signaling through dephosphorylation of phospho-BZR/BES, and is linked to regulation of seed size, seed development, reproductive structure development, and growth and developmental processes. It has been connected to response to stress and the mitotic cell cycle, and its product localizes to the cytosol, cytoplasm, and nucleus. Studies of related genes in other species link the family to protein phosphatase activity (EC 3.1.3.16).
