BIP4 — Camelina sativa

Summary

CSA12G051140, symbol BIP4 and also known as CsHSP70, encodes a member of the Hsp70 family of chaperones. The product possesses ATP hydrolase activity, binds ATP and heat shock proteins, and is a protein folding chaperone. In Camelina sativa, this gene is associated with protein folding in the endoplasmic reticulum, the ER unfolded protein response, the ERAD pathway, and protein refolding. It is linked to the MAPK cascade, signal transduction, and responses to stress, heat, salt, and viruses. Associations with pollen germination, pollen tube growth, and pollen development have also been observed. The protein localises to the ER lumen, ER chaperone complex, secretory vesicles, chloroplast membrane, tonoplast, and Golgi complex. Studies of related Hsp70 family members in other species link the family to thermotolerance, abiotic stress responses, and traits including seed weight, germination rate, and chlorophyll content.
