Fig. 5: Cricetidae and Muridae species share an evolutionarily novel FAM161A localization in their spermatozoa.

Rod protein localization in mature spermatozoan necks of house mice (a), deer mice (b), and prairie voles (c). Tubulin is used as a marker for the centriole and axoneme. PC proximal centriole, DC distal centriole, Ax axoneme. Scale bars are 1 µm. The images shown are representative of three independent experiments.
