Fig. 1: Location of FBXO47 in mouse spermatocytes.

a–e, a′–e′ Immunolocalization of SYCP3 (red) and FBXO47 (green) in mouse spermatocytes at the zygotene (a and a′), pachytene (b and b′), diplotene (c and c′), diakinesis (d and d′), and metaphase (e and e′) stages. f–i Immunolocalization of SYCP3 (blue), FBXO47 (green), and centromere (red) in Fbxo47+/+ (f) and Fbxo47−⁄− (i) spermatocytes. Detailed views of their location on autosomes (g) and the XY chromosomes (h) are provided. Chromosomes are outlined with dotted lines for clarity. Arrows indicate the FBXO47-positive ends of chromosomes, whereas arrowheads denote the FBXO47-negative ends. The PAR region is indicated for reference.
