HSP70 — Camelina sativa

Summary

CsHSP70-16 (CSA17G015740) on Camelina sativa chromosome 17 encodes a heat shock protein 70 family member with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. It is associated with protein folding in the endoplasmic reticulum, the ER unfolded protein response, the ERAD pathway, protein refolding, the MAPK cascade, signal transduction, and responses to stress, heat, and salt. The gene is linked to regulation of wax anabolism, pollen tube growth, seed setting rate, flower opening, and sepal heat stress response. Its product localizes to the ER lumen and chaperone complex, cytosol, cytoplasm, nucleus, tonoplast, membrane, mediator complex, and axonemal central pair projection. Studies of related genes in other species connect the family to reduced fertility, sepal fusion, altered wax profile, and high temperature stress response.
