Protein
Salt stress-responsive protein YocM
Organism
Bacillus subtilis (strain 168)
Function
Part of the cellular protein quality control system with a specific role in salt stress response. May facilitate protein homeostasis, together with chemical chaperones that accumulate during the salt stress response. Increased levels of YocM protects against both heat and salt stress. In vitro, displays an unusual aggregase chaperone activity.
Similarity
Belongs to the small heat shock protein (HSP20) family.
