HOP1 — Glycine max

Summary

GLYMA_17G137700V4, designated GmHOP1, encodes a member of the STI1/HOP family of co-chaperone proteins, containing TPR repeats and domains for Hsp70/Hsp90 binding. The gene product is annotated with preprotein, Hsp90, ubiquitin ligase, and chaperone protein binding, as well as protein serine/threonine phosphatase and kinase activities, ATP hydrolase activity, and DNA-binding transcription factor activity. GmHOP1 is associated with seed growth, chloroplast elongation, nutrient storage, protein processing, chaperone-mediated complex assembly, and responses to unfolded protein, cold, and low humidity. It is linked to flavonoid content, transpiration rate, stomatal resistance, drought tolerance, salt tolerance, oxidative stress response, high temperature stress response, and disease tolerance. The protein localizes to the nuclear membrane, ER membrane, plastid, plasmodesma, and stress granules. Related genes in other species are linked to jasmonic acid signaling, pathogen and herbivore resistance, and pollen germination.
