Monoclonal Mouse Affinity Purified E B
Activin isoforms and other members of the TGF­beta superfamily exert their biological effects by binding to heteromeric complexes of a type I and a type II serine­threonine kinase receptor, both of which are essential for signal transduction. To date, seven type I and five type II receptors, including the two type I and the two type II activin receptors, designated ActR­I(A), ActR­IB, ActR­II(A) and ActR­IIB, have been cloned from mammals. Through alternative mRNA splicing, multiple ActR­IIB isoforms can also be generated, adding to the complexity of the activin receptor system. Different activin isoforms bind with different high­affinities to the various type II isoforms. Type I activin receptors do not bind directly to activin, but will associate with the type II receptor­activin complex and initiate signal transduction. Besides the activin isoforms, ActR­II will also bind inhibin, BMP­2 and BMP­7 with lower affinities. ActR­I can also bind and form signaling complexes with the BMP­2/7­bound BMPR­II. Activin type II receptors are highly conserved. Human, mouse and rat type II activin receptors share greater than 98% amino acid sequence homology. Recombinant soluble activin type II receptors bind activin with high affinity, and are potent activin antagonists.
