B-1 — Sorghum bicolor

Summary

SORBI_3007G005400, also known as SbB-1, encodes a DnaJ-domain protein with ATPase activator activity and Hsp70 protein binding capacity, placing it in the HSP40/DnaJ chaperone family. The gene is associated with protein folding in the endoplasmic reticulum, protein refolding, and cellular response to heat, as well as defense response and response to thirst. Its product localizes to the ER lumen, vacuole, membrane, cytosol, nucleus, and plasmalemma. SbB-1 is associated with chlorophyll content and drought tolerance. Studies of related genes in other species further connect the family to stress responses and protein homeostasis.
