FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Cilia and flagella are comprised of a microtubular backbone, the axoneme, which is organized by the basal body and surrounded by plasma membrane. SPAG16 encodes 2 major proteins that associate with the axoneme of sperm tail and the nucleus of postmeiotic germ cells, respectively (Zhang et al., 2007 [PubMed 17699735]).[supplied by OMIM, Jul 2008]
PHENOTYPE: Chimeric males carrying one copy of the mutated allele have impaired spermatogenesis, a significant loss of germ cells at the round spermatid stage, and disorganized sperm axoneme structure. No offspring carrying the mutated allele are produced from matings using male chimeras. [provided by MGI curators]
