In the process of spermiogenesis, the proximal and distal centrioles translocate to the rear of the spermatid nucleus where the proximal centriole is attached, while the distal centriole elaborates the flagellum. The fluorescent centrin protein was seen to be located in basal body of flagellum. But the fluorescent spots could not be detected in the epididymal mature spermatozoa.
在精子变态分化过程中,近端和远端中心粒向核后方移动,近端中心粒附在核后膜上,远端中心粒伸出鞭毛,荧光显示Centrin蛋白位于伸出鞭毛的基部,但在成熟精子中该蛋白消失。

Spermatozoa of Hemicentrotus pulcherrimus belong to the type of flagelloform, it has a coniform cell nucleus on its head, a small apical body on its forepart, four mitochondria, a couple of central granules, and a flagellum.
海胆精子与其他无脊椎动物的精子一样,属于鞭毛型,其头部包含一个圆锥形的细胞核,前端配有一个小的顶体,还包括4个线粒体、一对中心粒和一根鞭毛。

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。

Peripheral plasma membrane proteins extracted from the spermatozoa from caput,corpus and cauda epididymis as well as vas deferens were probed with four lectins—Arachis hypogaea agglutinin、Canavalia ensiformis agglutinin、Dolichos biflorus agglutinin、Triticum vulgaris agglutinin.The results indicated that the 104 and 95kD AHA binding glycoproteins,and the 117、114、104、87、76、70kD ConA binding glycoproteins were synthesized and modified in the testis;the 120 and 65kD ConA binding glycoproteins,and the 54kD DBA binding glycoprotein were modified or lost during epididymal maturation;the 109kD ConA binding glycoprotein,the 74、70、45kD DBA binding glycoproteins,and the 57kD TVA binding glycoprotein were modified during epididymal maturation.
结果表明:与花生凝集素结合的104kD和95kD糖蛋白,与伴刀豆凝集素结合的117、114、104、87、76、70kD糖蛋白在睾丸中已完成了蛋白合成及修饰过程;与伴刀豆凝集素结合的120kD和65kD糖蛋白,与双花扁豆凝集素结合的54kD糖蛋白在精子附睾成熟过程中被修饰成其它种类的蛋白或被丢失;与伴刀豆凝集素结合的109kD糖蛋白,与双花扁豆凝集素结合的74、70、45kD糖蛋白,以及与麦胚凝集素结合的57kD糖蛋白是在附睾中完成其修饰过程的。
