PP2A — Brassica juncea

Summary

BJUB04G37270S (symbol PP2A, preferred name BjPP2A-2) encodes a protein belonging to the PPA2-like family with calcineurin-like phosphoesterase and metallo-dependent phosphatase domains, and exhibits protein serine/threonine phosphatase activity, protein phosphatase binding and regulator activity, kinase binding and kinase activity, and calcium-dependent protein serine/threonine kinase activity. The gene is associated with brassinosteroid signaling, TOR signaling, regulation of seed size, seed development, and reproductive structure development. It is linked to regulation of stomatal opening and closure, chloroplast avoidance movement, cellular responses to carbon dioxide and absence of light, and upregulation of abscisic acid-mediated signaling. Associations with agronomic traits include seed yield, biomass yield, water use efficiency, leaf elongation rate, root mass density, flowering time, and responses to osmotic stress, low temperature, and salt. The product localises to the cytosol, plasma membrane, cytoplasm, and nucleus.
