The function of Ensembl gene identifier ENSG00000196900 (SPMIP10, sperm microtubule inner protein 10) is as follows. Microtubule inner protein (MIP) part of the dynein-decorated doublet microtubules (DMTs) in flagellum axoneme, which is required for flagellum beating. May serve to reinforce and thus stabilize the microtubule structure in the sperm flagella. Involved in the regulation of sperm motility. .
