| 8. | A critical and central component is likely to be mpf ( m - phase promoting factor , another name is maturation - promoting factor , it was first discovered by masui and marikert in 1971 , and then purified from xenopus laevis eggs in 1988 P34 ~ ( cdc2 )有三个重要调节位点thr14 、 tyr15和thr161分别被其他各种因素调节,当thr161处于磷酸化,而thrl4 、 tyrls处于脱磷酸化时, p34抛才能被激活。 |
| 9. | Sequence alignment shows that the fragment of pcr product showed some identities to the masp gene of xenopus laevis , branchiostoma belcheri , the trypsin gene in litopenaeus vannamei and the serine protease gene in aurelia aurita Pcr反应产物基因片段大小为630bp ,序列比较结果表明, pcr克隆产物与爪蟾、文昌鱼的masp基因,虾、水母等的胰蛋白酶基因和丝氨酸蛋白酶基因都有一定的同源性。 |
| 10. | Mpf is a complex that consists of the protein kinase p34cdc2 and the regulatory protein cycli b ; the protein kinase activity of p34cdc2 is strictly dependent on its association with cyclinb . in xenopus laevis eggs the absent of cyclin b , mpf will not be activited Ca卜活化p34 ”拟的机制第一步是结合cycinb ,并且处于磷酸化状态,即thr14 、 tyrls和tlirl61都处于磷酸化状态;第二步是cdc25磷酸酶通过是thr14 、 tyr15脱磷酸化而激活p34 ”拟。 |
