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. This gene encodes activin A type I receptor which signals a particular transcriptional response in concert with activin type II receptors. Mutations in this gene are associated with fibrodysplasia ossificans progressive. [provided by RefSeq, Jul 2008]
[中文简述(自动翻译):]  激活素是属于转化生长因子-β(TGF-β)结构上相关的信号蛋白的超家族二聚生长和分化因子。活化素信号通过受体丝氨酸激酶的异聚复合物,其中包括至少两个I型(I和IB)和两个第二类(Ⅱ和ⅡB)受体。这些受体都是跨膜蛋白,具有富含半胱氨酸的区域,一个跨膜结构域,并与预测的丝氨酸/苏氨酸特异性的胞质域的配体 - 结合细胞外结构域组成。 I型受体为信号传导至关重要;和II型受体所必需的结合配体和I型受体的表达。 I型和II受体形成配位体后稳定的络合物结合,导致I型受体的磷酸化II型受体。该基因编码激活素这标志着在演唱与II型激活受体的特定转录反应I型受体。在这种基因突变与fibrodysplasia骨化渐进相关联。 [由RefSeq的,2008年7月提供]
