PP1 — Triticum turgidum subsp. durum

Summary

TRITD3BV1G027410, designated PP1 on durum wheat chromosome 3B, encodes a protein-serine/threonine phosphatase belonging to the PP1 catalytic subunit family, with metal-binding capability and protein serine/threonine phosphatase activity (EC 3.1.3.16). The gene is associated with signal transduction, auxin signaling, and the biological process GO:0016311. Its product localizes to both the cytoplasm and nucleus. Related genes in other species encode serine/threonine-protein phosphatases. The gene shares sequence similarity with homologs in barley, bread wheat, and other cereals, indicating evolutionary conservation of this phosphatase family across the Triticeae.
