PS2 — Pisum sativum

Summary

PsPS2, encoded by the garden pea gene PSAT4G047040 on chromosome 4LG4, is a presenilin-family protein containing Peptidase_A22A and Presenilin_C domains, with endopeptidase activity and protein-bridging function. It is associated with proteolysis, ectodomain cleavage, and protein processing, and localises to the presenilin complex, Golgi-associated vesicles, intracellular membrane-bounded organelles, and the nucleus. The gene has been connected to root mass density, root hair elongation, and phosphate starvation response and utilisation. Related genes in other species link the presenilin family to photochemical quenching.
