What is the Origin of GHR?

The abbreviation GHR is derived from the initial letters of 'Growth Hormone Receptor'. The receptor's existence was hypothesized and later confirmed as the mechanism by which the pituitary-derived Growth Hormone exerts its systemic effects. Understanding the GHR structure and function has been central to treating conditions of GH deficiency and resistance, forming a cornerstone of modern endocrinology.

What is the Mechanism of GHR?

The GHR functions as a single-pass transmembrane protein that exists as a pre-formed dimer or is dimerized upon binding of the Growth Hormone molecule. Hormone binding triggers a conformational change that activates the intracellular Janus kinase 2 (JAK2) enzyme, which is constitutively associated with the receptor. Activated JAK2 then phosphorylates various downstream substrates, initiating the JAK-STAT signaling pathway, leading to gene transcription and the production of Insulin-like Growth Factor 1 (IGF-1) in the liver.

GHR

Meaning

GHR is the acronym for the Growth Hormone Receptor, a transmembrane protein found on the surface of cells in various tissues, notably the liver, muscle, and adipose tissue. This receptor is the principal mediator of the biological actions of Growth Hormone (GH), initiating intracellular signaling pathways upon hormone binding. The density and function of GHRs are crucial determinants of an individual’s sensitivity and responsiveness to circulating GH, impacting growth, metabolism, and body composition.
