Predicted to enable protein folding chaperone; ubiquitin protein ligase binding activity; and unfolded protein binding activity. Acts 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 several cellular components, including acrosomal vesicle; heterochromatin; and pericentriolar material. Part of chaperonin-containing T-complex and zona pellucida receptor complex. Is expressed in several structures, including cerebral cortex; extraembryonic component; genitourinary system; humerus; and immune system. Orthologous to human TCP1 (t-complex 1).
