HSP70 — Camelina sativa

Summary

CsHSP70-16 (CSA14G014450) on chromosome 14 of Camelina sativa encodes a member of the Hsp70 family, characterized by an N-terminal ATPase domain and a C-terminal peptide-binding domain, with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. The gene is associated with protein folding in the endoplasmic reticulum, the ER unfolded protein response, the ERAD pathway, the MAPK cascade, signal transduction, and responses to stress, heat, salt, and salinity. It is linked to regulation of wax anabolism, pollen tube growth, and seed setting rate, as well as heat stress tolerance and flower opening. The product localizes to the ER lumen, ER chaperone complex, cytosol, cytoplasm, nucleus, membrane, tonoplast, and axonemal central pair projection. Related genes in other species are linked to spikelet fertility, high temperature stress response, and altered wax profiles with reduced fertility and sepal fusion.
