This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 14.5 kDa. The protein migrates as 20-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
纯度(Purity)
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
激活素受体2B型(ACVR2B)也称为ActR IIB和MGC116908,ACVR2B是激活素2型受体。激活素是二聚体生长和分化因子,属于结构相关信号蛋白的转化生长因子-β(TGF-β)超家族。激活素通过受体丝氨酸激酶的异质复合物发出信号,所述受体丝氨酸激酶包括至少两种I型(I和IB)和两种II型(II和IIB)受体。这些受体都是跨膜蛋白,由具有半胱氨酸富集区的配体结合胞外结构域、跨膜结构域和具有预测丝氨酸/苏氨酸特异性的细胞质结构域组成。I型受体对信号传导至关重要;并且II型受体是结合配体和表达I型受体所必需的。I型和II型受体在配体结合后形成稳定的复合物,导致I型受体被II型受体磷酸化。II型受体被认为是组成型活性激酶。该基因编码激活素A IIB型受体,其对配体的亲和力是激活素II型受体的3-4倍。ACVR2B缺陷是常染色体4型内脏异轴畸形(HTX4)的病因。
