FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an activin A type IB 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 and two type II receptors. This protein is a type I receptor which is essential for signaling. Mutations in this gene are associated with pituitary tumors. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Jun 2010]
PHENOTYPE: Embryos homozygous for targeted mutations that inactivate the gene arrest at the egg cylinder stage, prior to gastrulation, showing epiblast and extraembryonic ectoderm disorganization. [provided by MGI curators]
