Background :
Activin receptor type-2B (ACVR2B) is also known as ActR-IIB and MGC116908, ACVR2B is an activin type 2 receptor. Activins are dimeric growth and differentiation factors which belong to the transforming growth factor-beta (TGF-beta) superfamily of structurally related signaling proteins. Activins signal through a heteromeric complex of receptor serine kinases which include at least two type I (I and IB) and two type II (II and IIB) receptors. These receptors are all transmembrane proteins, composed of a ligand-binding extracellular domain with cysteine-rich region, a transmembrane domain, and a cytoplasmic domain with predicted serine/threonine specificity. Type I receptors are essential for signaling; and type II receptors are required for binding ligands and for expression of type I receptors. Type I and II receptors form a stable complex after ligand binding, resulting in phosphorylation of type I receptors by type II receptors. Type II receptors are considered to be constitutively active kinases. This gene encodes activin A type IIB receptor, which displays a 3- to 4-fold higher affinity for the ligand than activin A type II receptor. Defects in ACVR2B are the cause of visceral heterotaxy autosomal type 4 (HTX4).

ACROBiosystems is a leading manufacturer of recombinant proteins and other critical reagents to support the development of target therapeutics, vaccines and diagnostic kits.

Our team has worked tirelessly since the genomic sequence of SARS-CoV-2 was first published, developing a serial of critical reagents to fight COVID-19. Our team has successfully developed a new neutralizing antibody titer serologic assay kit for COVID-19 vaccine evaluation (Cat.No.TAS-K022) which really showed excellent performance.

As the emerging variants may have impacted on the development of the COVID-19 epidemic, our team is also going full steam ahead on developing a collection of spike mutants for the emerging variants of SARS-COV-2. The reagents can be used to evaluate the efficacy of the antibodies and vaccination.

We have also developed an extensive collection of recombinant proteins to support the development for bispecific antibodies, antibody drug conjugates and cell therapies.
