Fsip2 Gene Summary [Rat]
Predicted to act upstream of or within with a positive effect on protein localization to cilium and sperm axoneme assembly. Predicted to be located in sperm flagellum and sperm head-tail coupling apparatus. Human ortholog(s) of this gene implicated in spermatogenic failure 34. Orthologous to human FSIP2 (fibrous sheath interacting protein 2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Fsip2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
