Scientific Data Images for Human Activin RIIA Antibody

Detection of Human Activin RIIA antibody by Western Blot.

Detection of Human Activin RIIA by Western Blot.

Western blot shows lysates of human testis tissue. PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human Activin RIIA Monoclonal Antibody (Catalog # MAB340) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Activin RIIA at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Activin RIIA

Activin isoforms and other members of the TGF-beta  superfamily exert their biological effects by binding to heteromeric complexes of a type I and a type II serine‑threonine 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 ActR-I(A), ActR-IB, ActR-II(A) and ActR-IIB, have been cloned from mammals. Through alternative mRNA splicing, multiple ActR-IIB isoforms can also be generated, adding to the complexity of the activin receptor system. Different activin isoforms bind with different high-affinities to the various type II isoforms. Type I activin receptors do not bind directly to activin, but will associate with the type II receptor-activin complex and initiate signal transduction. Besides the activin isoforms, ActR-II will also bind inhibin, BMP-2 and BMP-7 with lower affinities. ActR-I can also bind and form signaling complexes with the BMP-2/7-bound BMPR-II. 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.
