There are two main types of growth hormone (GH) in the circulatory system. One is 22 kD-GH, which is the predominant isoform in the circulating system, 90% GH is present as a 22 kD protein, and 10% of GH is present as a 20 kD protein.

In the inactive homodimeric GHR, (A) the Janus kinase (JAK) 2 kinase domain (KD) is inhibited in trans by interaction with the pseudokinase domain from the JAK2 bound to the opposing receptor within the homodimer.

生长激素受体（英語： Growth hormone receptor)是一种由人类基因GHR 编码的蛋白质 [1] ，GHR的直系同源物 [2] 广泛存在于各种哺乳动物中。 此基因编码的蛋白是结合 生长激素 的跨膜受体。

2002年7月8日 · In this study, ligand-independent GHR dimerization is demonstrated in the endoplasmic reticulum and at the cell surface by coimmunoprecipitation of an epitope-tagged truncated GHR with wild-type GHR. In addition, evidence is provided that the extracellular domain of the GHR is not required to maintain this interaction.

2019年2月8日 · In adults, hypersecretion of GH causes acromegaly, and strategies that block the release of GH or that inhibit GH receptor (GHR) activation are the primary forms of medical therapy for this...

2023年5月9日 · 研究表明JAK2和LYN之间直接竞争GHR结合，这意味着它们会产生不同的信号传递方式。 此外，研究人员还发现GHR在细胞膜中存在不同的运动状态，并且激活LYN可以介导GHR的固定，从而在膜中形成纳米聚类。 重要的是，研究人员还观察到LYN介导细胞因子受体的降解，从而控制受体的周转和活性。 这些发现对于许多细胞因子受体都具有广泛的相关性。 这项研究的创新点在于发现了LYN与GHR之间的分子相互作用，并且强调了LYN在调节GHR纳米聚 …

这篇综述概述了有关gh作用的分子机制的最新知识。提出的模型是其中gh与两个ghr结合导致ghr的二聚化，与ghr相关的jak2酪氨酸激酶的激活以及jak2和ghr的酪氨酰磷酸化的模型。

Growth hormone (GH) actions via initiating cell signalling through the GH receptor (GHR) is important for many physiological processes, in addition to its well-known role in regulating growth. The activation of JAK-STAT signalling by GH is well characterized, however knowledge on GH activation of SRC family kinases (SFKs) is still limited.

垂体中生长激素（GH）的分泌受两种下丘脑肽的控制：GH释放激素 (GHRH)和生长激素释放抑制激素因子 (SRIF)。 GHRH是GH的主要调控因子，促进GH基因的转录和释放；生长抑素通过抑制生长激素对GHRH的生长营养反应来抑制生长激素的分泌。 第三个因素是 胃饥饿素，它对生长激素分泌具有刺激作用，尽管它在生长激素分泌的生理调节中所起的作用存在争议 [4]。 除此之外，影响生长激素分泌的因素还有很多，如年龄、性别、饮食、运动、压力和其他激素。 葡萄糖和 …
