hsp-16.1 encodes a 16-kD heat shock protein (HSP) that is a member of the hsp16/hsp20/alphaB-crystallin (HSP16) family of heat shock proteins, and that is identical to the protein encoded by hsp-16.11; an hsp-16.1 reporter fusion, expressed broadly but most strongly in muscle and hypodermis, is induced solely in response to heat shock or other environmental stresses; expression is detectable in somatic tissues in post-gastrulation embryos, all larval stages, and in adults; HSP-16.1 is likely to function as a passive ligand temporarily preventing unfolded proteins from aggregating.
Predicted to enable unfolded protein binding activity. Involved in defense response to Gram-negative bacterium and response to heat. Located in Golgi medial cisterna. Expressed in several structures, including coelomocyte; enteric muscle; intestine; pharynx; and ventral nerve cord.

C. elegans is an effective model system to study heat-related pathologies like heat stroke; in elegans, a small heat shock protein (sHSP), HSP-16.1 has a protective effect against heat-induced necrosis; HSP-16.1 localizes to the golgi and functions together with the PMR-1/PMR1 Ca2+ and Mn2+ transporting ATPase, and NUCB-1/Nucleobindin1, a golgi-located calcium-buffering protein, to maintain calcium homeostasis, under heat stroke; overexpresiion of pmr-1/PMR1 is sufficient to promote survival after heat stroke, bypassing both HSF-1 and HSP-16.1, indicating that PMR-1/PMR1 functions downstream of both these genes.
