It was a new mousegene in GenBank and named as SRG-L(spermatogenesis related gene expressed in the latestages of spermatogenic cells). The sequence of this cDNA has been deposited in GenBankwith the Accession No. AY352586. 2. Analyses of expression characteristics of SRG-L during mouse spermatogenesis.The results of RT-PCR and Northern Blotting indicated that no expression signal of thisgene could be observed in primitive type A spermatogonia and type B spermatogonia. Asignal first appeared in diplotene/pachytene spermatocytes, and was significantlyintensified in round spermatids and elongating spermatids, findly went down to beundetectable in mature spermatozoa.

RT-PCR和Northern Blotting分析表明：该基因在早期A型和B型精原细胞中不表达，从双线期初级精母细胞阶段开始表达并逐渐上调，在粗线期初级精母细胞、圆形精子细胞及长形精子细胞中均检测到高水平的mRNA，但在成熟精子中消失，具有明显的阶段特异性表达特征，并且组织特异性表达分析显示该基因在睾丸组织中的呈高表达。
