HSC-2 — Capsicum annuum

Summary

T459_23072 (symbol HSC-2, also known as CaHSP70) on pepper chromosome 9 encodes an uncharacterized protein of the Hsp70 family, 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, protein refolding, the ERAD pathway, the ER unfolded protein response, stress responses including response to heat and virus, virus-induced post-transcriptional gene silencing, cell death, ABA signaling, signal transduction, and defense response. It has been connected to fruit length and plant height. The encoded protein localizes to the ER chaperone complex, ER lumen, chloroplast membrane, tonoplast, membrane, cytoplasm, and nucleus. Studies of related Hsp70 family members in other species link the family to seed weight, seed size, lignin content, stomatal resistance, and chlorophyll content.
