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 a 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.
The gene for ACVR1B (activin A type IB receptor) is composed of 11 exons.
Alternative splicing and alternative polyadenylation result in 3 fully described transcript variants.
The mRNA expression of variants 1, 2, and 3 is confirmed, and a potential fourth variant contains an alternative exon 8 and lacks exons 9 through 11, but its mRNA expression has not been confirmed.
