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