Abstract

The receptor system and the molecular mechanisms by which inhibin acts on its target cells are poorly understood, in contrast to the situation for the structurally related molecule, activin. On the basis of evidence that the biological action of inhibin in a number of systems resembles that of an activin antagonist, it has been contended that inhibin operates by competition for the activin receptor rather than through a specific inhibin receptor. However, mounting evidence indicates that inhibin also interacts with high affinity and specificity with membrane-binding proteins that are likely to be the putative inhibin receptor.

抑制素的作用是通过一种独特的受体介导的吗?
与结构相关的分子激活素相比,抑制素作用于靶细胞的受体系统和分子机制尚不清楚。基于抑制素在许多系统中的生物作用类似于激活素拮抗剂的证据,人们认为抑制素是通过竞争激活素受体而不是通过特定的抑制素受体起作用的。然而,越来越多的证据表明抑制素也与膜结合蛋白具有高亲和力和特异性相互作用,这些膜结合蛋白可能是假定的抑制素受体。
