BMPRIB/ALK-6 蛋白, Human (sf9, His-GST)

BMPR1B/ALK-6 protein is a type I member of the bone morphogenetic protein (BMP) receptor family of transmembrane serine/threonine kinases^[1]. BMPR1B/ALK-6 is the receptor for BMP-7/OP-1 and GDF-5, positively regulates chondrocyte differentiation through GDF-5 interaction^[2][3]. BMPR1B/ALK-6 also involves in SCUBE3/BMP-2/BMP-4 signals regulation, controlling growth, morphogenesis, and bone and teeth development^[4]. ALK-6/GDF-9/BMP-15 signals is essential in prolificacy of goat^[5]. The human BMPR1B/ALK-6 protein contains 502 amino acids and a transmembrane domain (127-148 a.a.). BMPRIB/ALK-6 Protein, Human (sf9, His-GST) is produced by HEK293 cells (R149-L502) with N-terminal His- and GST-tag.

BMPRIB/ALK-6，也称为 CDw293（分化簇 w293），是跨膜丝氨酸/苏氨酸激酶的骨形态发生蛋白 (BMP) 受体家族的成员。BMP 参与软骨内骨形成和胚胎发生，通过形成两种类型 BMP 受体的异聚复合物来转导信号：I 型受体 (50-55 kD) 和 II 型受体 (70-80 kD)。II 型受体磷酸化并激活 I 型受体，I 型受体自身磷酸化，然后结合并激活 SMAD 转录调节因子^[1]。ALK-6 是 BMP-7/OP-1 和 GDF-5 的受体，通过 GDF-5 相互作用正向调节软骨细胞分化^[2][3]。ALK-6 信号传导还受 BMP-2/BMP-4 共受体 SCUBE3 控制，将 BMP 受体复合物招募到筏微域中，并可能通过增强 BMP 和 BMP I 型受体之间的特异性相互作用来正向调节信号传导^[3]。ALK-6 通过调节 BMP 信号传导参与控制生长、形态发生以及骨骼和牙齿发育，对于体内软骨形成至关重要，而 BMPR1A/ALK-3 和 ALK-6 在早期软骨形成过程中具有重叠功能^[4] 。ALK-6/GDF-9/BMP-15 信号在繁殖中发挥关键作用。ALK-6 和 GDF-9 广泛表达于 20 种组织中，其中卵巢表达最高，而 BMP-15 基因仅在卵巢和垂体中表达^[5]。ALK-6的序列在不同物种之间高度保守，人类的序列分别与大鼠（98.21%）和小鼠（98.21%）具有很高的相似性。
