Fbxl13 and Drc7 are evolutionarily conserved and testis-enriched genes.

(A) Model of DRC localization, based on Chlamydomonas [13,14]. The numbers shown in the N-DRC correspond to each DRC component. FBXL13 (DRC6) and DRC7 are located next to TCTE1 (DRC5). (B) The expression of mouse Fbxl13 and Drc7 was examined by RT-PCR using RNA isolated from various organs. Both Fbxl13 and Drc7 are testis-enriched with weak expression detected in other tissues. Actb was used as a loading control. (C) The expression of Fbxl13 and Drc7 was examined by RT-PCR using RNA isolated from testis at various postnatal days. Actb was used as a loading control.
