Webb23 mars 2000 · It is shown that inhibin blocks cellular responses to diverse BMP family members in a variety of BMP-responsive cell types, suggesting a broader role for inhibin and betaglycan in restricting and refining a wide spectrum of transforming growth factor β superfamily signals. 172 PDF Webb1 feb. 2002 · Recently, additional inhibin binding proteins were identified in inhibin target tissues, including pituitary and Leydig cells. Characterization of these proteins, coupled with ongoing investigations of betaglycan and InhBP/p120, will lead to a clearer understanding of mechanisms of inhibin action.

Within the cell, the junctions of the pro- and mature domains (red arrowheads) are cleaved by pro-protein convertases, leaving the noncovalent interactions among the domains intact.

When produced, it helps to suppress another hormone called FSH, or follicle … WebbInhibins are structurally related to activins by sharing the same β-subunit. It is well documented that inhibins block many actions of activins and function as activin antagonists. Several studies have shown that inhibins can bind to ActR-IIA and, therefore, antagonize activin actions.
