Rfx2 | DNA-binding protein RFX2; Transcription factor that acts as a key regulator of spermatogenesis. Acts by regulating expression of genes required for the haploid phase during spermiogenesis, such as genes required for cilium assembly and function. Recognizes and binds the X-box, a regulatory motif with DNA sequence 5'-GTNRCC(0-3N)RGYAAC-3' present on promoters. Probably activates transcription of the testis-specific histone gene HIST1H1T. Belongs to the RFX family. (717 aa) | ||||
Rsph1 | Radial spoke head 1 homolog; The specific expression during male germ cell development and its characteristic localization suggest that it may play an important role in male meiosis. It is necessary for proper building of the axonemal central pair and radial spokes (By similarity). (301 aa) |
