Is predicted to encode a protein with the following domains: UNC-45/Cro1/She4, central domain; Armadillo-like helical; Tetratricopeptide-like helical domain superfamily; Myosin-binding striated muscle assembly central; Armadillo-type fold; and Tetratricopeptide repeat. Is an ortholog of C. elegans unc-45. In C. elegans, unc-45 is involved in several processes, including egg-laying behavior; protein folding; and sarcomere organization.
