What is GHRL?
A 28-amino-acid peptide hormone best known for stimulating appetite and growth hormone release via GHSR1a. It also modulates glucose metabolism, gastrointestinal motility, and MAPK/AMPK-linked signaling.

Research Summary
An important endogenous peptide in energy balance and neuroendocrine control. Ghrelin signaling remains an active area of research for obesity, cachexia, and metabolic disease.
Related Peptides
IGF-1
Insulin-like growth factor 1
A 70-amino-acid peptide that signals through IGF1R to activate PI3K/AKT and MAPK pathways. It mediates anabolic growth, cell survival, and tissue repair in endocrine and local paracrine signaling.
Signal PeptidesAVP
Arginine vasopressin
A nonapeptide hormone that acts at V1 and V2 receptors to regulate vascular tone and renal water reabsorption. It is a core mediator of osmotic homeostasis and blood pressure control.
Signal PeptidesBK
Bradykinin
A nonapeptide generated from kininogen during inflammation and tissue injury. It activates B1/B2 receptors to produce vasodilation, pain, and vascular permeability.
Signal PeptidesANG II
Angiotensin II
An 8-amino-acid peptide hormone that binds angiotensin receptors to drive vasoconstriction, aldosterone release, and thirst. It is a major signaling effector of the renin-angiotensin system.
