Spermatogenesis Associated Protein 24 (SPATA24)

T6441, initially derived by the suppressive subtracted hybridization (SSH) cDNA library. The full-length T6441cDNA was 664 bp long, containing a complete open-reading frame for a protein of 149 amino acids (aa). The protein bears no homology to any reported genes. It is predicted that the molecular mass was about 16.7 kDa. Northern blot analysis showed that the T6441 gene had about 4 transcripts in adult rat testis and was temporally regulated in a stage-dependent manner in the testis. In situ hybridization showed that T6441 mRNA was specifically localized in spermatids, and its expression level varied in the cells at different stages of the testicular development, with the highest level at steps 7-14. RT-PCR results showed that the T6441 mRNA was transcribed in most of the tested tissues with its strongest signal in the testis.
