Using the ActR IB and ActR IIB receptor isoforms , we have investigated the mechanism of activin receptor activation . ^^^ Activin binds directly to ActR IIB , and this complex associates with ActR IB , which does not bind ligand on its own . ^^^ In the resulting complex , ActR IB becomes hyperphosphorylated , and this requires the kinase activity of ActR IIB . ^^^ Furthermore , the signalling activity of this mutant construct is undisturbed by overexpression of a dominant negative kinase defective ActR IIB construct , indicating that ActR IB ( T206D ) can signal independently of ActR IIB . ^^^ The evidence suggests that ActR IIB acts as a primary activin receptor and ActR IB acts as a downstream transducer of activin signals . . ^^^ |

Previous studies have demonstrated that primary ovine pituitary cells express different activin receptor subtypes : activin receptor like ( ALK ) 2 , ALK 4 , activin type 2 receptor A ( ActRIIA ) , ActRIIB and Smad proteins in vitro . ^^^ Using Northern blots , we have shown that the levels of ALK 2 , ALK 4 and ActRIIB mRNA were significantly higher before the preovulatory surge and during the secondary surge of FSH as compared with both during the preovulatory surge and the luteal phase , whereas the level of the ActRIIA mRNA was similar throughout the oestrous cycle . ^^^ |
