Spag1 Gene Summary [Mouse]
Predicted to enable GTP binding activity and hydrolase activity. Predicted to be involved in axonemal dynein complex assembly. Predicted to be located in cytoplasm. Predicted to be part of protein folding chaperone complex. Predicted to be active in cytosol. Is expressed in several structures, including blastocyst; early embryo; foregut; gonad; and skin. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 28. Orthologous to human SPAG1 (sperm associated antigen 1). [provided by Alliance of Genome Resources, Apr 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 mouse Spag1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

- Tetratricopeptide repeats
- mitochondrial import receptor subunit TOM70
- tetratricopeptide repeat
