Predicted to enable protein folding chaperone; ubiquitin protein ligase binding activity; and unfolded protein binding activity. Predicted to be involved in several processes, including positive regulation of DNA biosynthetic process; positive regulation of protein localization; and positive regulation of telomerase RNA localization to Cajal body. Predicted to act upstream of or within several processes, including binding activity of sperm to zona pellucida; toxin transport; and translocation of peptides or proteins into host cell cytoplasm. Located in heterochromatin. Orthologous to human TCP1 (t-complex 1). [provided by Alliance of Genome Resources, Apr 2022]
