OPT3 — Pisum sativum

Summary

PSAT2G182800 (symbol OPT3, preferred name PsOPT3) on garden pea chromosome 2LG1 encodes a protein with an oligopeptide transporter domain and exhibits transition metal ion transmembrane transporter activity and oligopeptide transmembrane transporter activity. The gene is associated with xylem-to-phloem iron transport, cellular monoatomic cation homeostasis, and multicellular organismal iron ion homeostasis. It is associated with iron homeostasis, cadmium distribution and partitioning, disease resistance, iron acquisition gene expression, and iron mobilization. The encoded protein localises to the plasmodesma, membrane, cytosol, plasmalemma, and cytoplasm. Related genes in other species link the family to iron transport, copper transport, metal homeostasis, embryo development, seed iron content, and cadmium accumulation in seeds.
