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