Is predicted to encode a protein with the following domains: CHIP, N-terminal tetratricopeptide repeat domain; Tetratricopeptide repeat 2; Tetratricopeptide repeat; Tetratricopeptide repeat 1; Tetratricopeptide-like helical domain superfamily; and CHIP N-terminal tetratricopeptide repeat domain. Is an ortholog of C. elegans chn-1. In C. elegans, chn-1 is involved in several processes, including determination of adult lifespan; egg-laying behavior; and protein ubiquitination.
