HSP70-16 — Cicer arietinum

Summary

LOC101508236 (CaHSP70-16) on chickpea chromosome 5 encodes a heat shock 70 kDa protein family member with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. This gene is associated with the endoplasmic reticulum chaperone complex, ER lumen, tonoplast, membrane, cytoplasm, and nucleus. It is linked to protein folding in the ER, the ERAD pathway, the unfolded protein response, protein refolding, and responses to heat, stress, and defense. CaHSP70-16 is also associated with regulation of wax anabolism, flavonoid anabolism, pollen tube growth, drought tolerance, seed setting rate, flower opening, and heat stress tolerance. Studies of related heat shock 70 kDa proteins in other species link the family to spikelet fertility, high temperature stress response, seed maturation, and altered wax profiles.
