Ropn1 - ropporin, rhophilin associated protein 1

Predicted to enable identical protein binding activity and protein heterodimerization activity. Acts upstream of or within several processes, including flagellated sperm motility; protein localization to cilium; and sperm capacitation. Located in sperm cytoplasmic droplet and sperm principal piece. Orthologous to human ROPN1 (rhophilin associated tail protein 1) and ROPN1B (rhophilin associated tail protein 1B).
