Predicted to enable several functions, including G-protein beta-subunit binding activity; beta-tubulin binding activity; and mRNA binding activity. Acts upstream of or within binding activity of sperm to zona pellucida and toxin transport. Located in cell body. Part of chaperonin-containing T-complex and zona pellucida receptor complex. Is expressed in 1st branchial arch mandibular component and mandible primordium. Orthologous to human CCT5 (chaperonin containing TCP1 subunit 5). [provided by Alliance of Genome Resources, Apr 2022]
