Is predicted to encode a protein with the following domains: HSP20-like chaperone; Alpha crystallin/Hsp20 domain; Hsp20/alpha crystallin family; and Alpha crystallin/Small heat shock protein, animal type. Is an ortholog of C. elegans F08H9.4; F08H9.3; and
hsp-16.2. In C. elegans,
hsp-16.1 is involved in defense response to Gram-negative bacterium; endoplasmic reticulum unfolded protein response; and response to heat.
