PP1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G252260 (symbol PP1) on durum wheat chromosome 5B 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 fold. The product possesses protein serine/threonine phosphatase activity and metal binding, and is associated with the biological processes of signal transduction, auxin signaling, and protein dephosphorylation (GO:0016311). It localizes to both the cytoplasm and nucleus. Related genes in other species link the family to auxin-mediated growth and stress signaling, though these functions are not yet established in durum wheat.
