PP1 — Triticum turgidum subsp. durum

Summary

TRITD3BV1G027430, designated PP1 on durum wheat chromosome 3B, encodes a protein serine/threonine phosphatase (EC 3.1.3.16) belonging to the PP1 catalytic subunit family, with a metallo-dependent phosphatase-like domain and calcineurin-like phosphoesterase core. The product possesses protein serine/threonine phosphatase activity and metal binding, and is associated with signal transduction, auxin signaling, and protein dephosphorylation. It localises to both the cytoplasm and nucleus. Studies of related genes in other species link the family to diverse cellular signalling pathways, though these associations are not yet established for this specific durum wheat gene.
