该基因编码跨膜丝氨酸/苏氨酸激酶骨形态发生蛋白（BMP）受体家族的一个成员。这种受体的配体是bmps，它是tgf-β超家族的成员。bmps参与软骨内骨形成和胚胎发生。这些蛋白质通过两种不同类型的丝氨酸（苏氨酸）激酶受体的异聚物复合物的形成传递信号：约50-55kd的Ⅰ型受体和约70-80kd的Ⅱ型受体。在没有I型受体的情况下，II型受体结合配体，但它们需要各自的I型受体进行信号传递，而I型受体需要各自的II型受体进行配体结合。该基因突变与原发性肺动脉高压（家族性和芬氟拉明相关性）和肺静脉阻塞性疾病有关[由RefSeq提供，2008年7月]
This gene encodes a member of the bone morphogenetic protein (BMP) receptor family of transmembrane serine/threonine kinases. The ligands of this receptor are BMPs, which are members of the TGF-beta superfamily. BMPs are involved in endochondral bone formation and embryogenesis. These proteins transduce their signals through the formation of heteromeric complexes of two different types of serine (threonine) kinase receptors: type I receptors of about 50-55 kD and type II receptors of about 70-80 kD. Type II receptors bind ligands in the absence of type I receptors, but they require their respective type I receptors for signaling, whereas type I receptors require their respective type II receptors for ligand binding. Mutations in this gene have been associated with primary pulmonary hypertension, both familial and fenfluramine-associated, and with pulmonary venoocclusive disease. [provided by RefSeq, Jul 2008]
