Is predicted to encode a protein with the following domains: STI1 domain; Tetratricopeptide repeat 2; Tetratricopeptide-like helical domain superfamily; Heat shock chaperonin-binding; Tetratricopeptide repeat; and TPR repeat. Is an ortholog of C. elegans
sti-1. In C. elegans,
sti-1 is involved in determination of adult lifespan and response to heat.
