项目摘要
Sperm motility-initiating substance is a nonglycosilated protein that acts specifically in the mode of internal fertilization of the urodele amphibian, Cynops pyrrhogaster. In the present study, a cDNA encoding SMIS protein was identified. It coded a sequence of 151 amino acids that contained a cysteine knot domain. The expression of the SMIS gene was oviduct-specific and independent of the stimuli of ovulation. The active site of the SMIS was detected in a hydrophilic loop of the cysteine knot domain using synthetic peptides having partial amino acid sequences of the SMIS. Immunoblotting and southernblotting revealed that proteins homologous to SMIS were widely conserved among anuran and urodele amphibians but those homologues showed different isoelectric points ranging from 4 to 7. These results suggest that the molecular feature of the SMIS may be changed in adaptation to the diversified fertilization modes among amphibian species.
精子运动发射物质是一种非糖化蛋白,该蛋白质专门起作用尿毒菌(Cynops cynops pyrrhogaster)内部受精方式。在本研究中,确定了编码SMIS蛋白的cDNA。它编码了151个氨基酸的序列,其中包含半胱氨酸结域。 SMIS基因的表达是产卵特异性的,并且独立于排卵刺激。使用具有SMI的部分氨基酸序列的合成肽,在半胱氨酸结域的亲水环中检测到SMI的活性位点。免疫印迹和南部印迹表明,与SMI同源的蛋白质在Anuran和Urodele两栖动物中广泛保存,但这些同源物显示出不同的等电点,这些结果范围为4至7。
