骨形态发生蛋白（bmp）受体是一个跨膜丝氨酸/苏氨酸激酶家族，包括Ⅰ型受体bmpr1a和bmpr1b和Ⅱ型受体bmpr2。这些受体还与激活素受体acvr1和acvr2密切相关。这些受体的配体是tgf-β超家族的成员。转化生长因子β和激活素通过与两种不同类型的丝氨酸（苏氨酸）激酶受体形成异聚物复合物来传递信号：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。[由RefSeq提供，2008年7月]
The bone morphogenetic protein (BMP) receptors are a family of transmembrane serine/threonine kinases that include the type I receptors BMPR1A and BMPR1B and the type II receptor BMPR2. These receptors are also closely related to the activin receptors, ACVR1 and ACVR2. The ligands of these receptors are members of the TGF-beta superfamily. TGF-betas and activins transduce their signals through the formation of heteromeric complexes with 2 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.
