HSP90 — Pisum sativum

Summary

PSAT5G026960 (HSP90) on garden pea chromosome 5LG3 encodes an ATP-dependent protein folding chaperone with ATP hydrolase and ATP binding activities, belonging to the Hsp90 family and containing a ribosomal S5 D2-type superfamily domain. This gene is associated with diverse biological processes including protein folding, maturation, import, and targeting, as well as photorespiration, stress response, seed germination, jasmonic acid signaling, proteolysis, cell cycle, cell division, and signal transduction. It is associated with sperm motility, capacitation, acrosome reaction, and S-nitrosylation, and is linked to relative growth rate. The encoded protein localizes to the endoplasmic reticulum lumen. Related genes in other species identify the family as HSP90 and a GRP-94 homolog.
