Is predicted to encode a protein with the following domains: Tetratricopeptide repeat; Tetratricopeptide-like helical domain superfamily; STI1 domain; TPR repeat; Heat shock chaperonin-binding; and Heat shock protein Sti1-like. Is an ortholog of C. elegans
sti-1. In C. elegans,
sti-1 is involved in determination of adult lifespan and response to heat.
