ACTH 1-34

Description

Overview of ACTH 1–34

ACTH 1‑34 is a peptide fragment of the full adrenocorticotropic hormone (ACTH). It binds selectively to melanocortin receptors on adrenal cortical cells, triggering intracellular signaling pathways. This fragment is used exclusively as a research tool to study receptor-ligand interactions and molecular signaling within adrenal-like systems.

ACTH 1-34 Mechanism 

ACTH 1–34 binds selectively to melanocortin 2 receptors (MC2R) on adrenal-like cells. Binding induces a conformational change in the receptor, activating the associated Gs protein and stimulating adenylate cyclase. This increases intracellular cyclic AMP (cAMP), which activates protein kinase A (PKA). PKA phosphorylates target proteins, including transcription factors, to regulate genes involved in steroidogenic enzyme production.

Key Molecular Insights:

• Signal transduction: Converts extracellular receptor binding into intracellular biochemical signals.
• Enzyme regulation: PKA-mediated phosphorylation controls steroidogenic enzyme activity.
• Receptor specificity: Demonstrates selective engagement of MC2R compared to other melanocortin receptors.

Research Application on ACTH 1-34

ACTH 1‑34 is used as a research tool in cellular and molecular studies to probe:

• Receptor-ligand binding dynamics at melanocortin receptors.
• Intracellular signaling pathways mediated by cAMP and PKA.
• Transcriptional regulation of steroidogenic enzymes.
• Structure-function relationships of peptide hormones.
