The Origin and Nature of the TLQP-21 Peptide

The TLQP-21 peptide is generated through the proteolytic cleavage of the VGF pro-peptide, a protein widely expressed in neuroendocrine cells. This process yields a family of peptides, with TLQP-21 being one of the most extensively studied. Its designation as a neuropeptide TLQP-21 highlights its presence and function within the nervous system, specifically in sympathetic nerve terminalsVFG-Derived Peptide TLQP-21 - Bartolomucci Lab. The TLQP-21 peptide acts as a signaling molecule, mediating communication between cells and influencing a range of cellular and systemic responses. The fact that it is a peptide of 21 amino acids provides a specific structural characteristic that underpins its interactions with biological targets.

Key Biological Functions and Mechanisms of Action

Research has revealed that TLQP-21 is a potent activator of the G-protein-coupled receptor C3aR1作者：G Corda·2021·被引用次数：8—TheTLQP-21 peptidepotentiates glucose-stimulated insulin secretion, hence we investigated its endogenous response to glucose.. This interaction often occurs via a folding-upon-binding mechanism, indicating a dynamic relationship between the peptide and its receptor. This activation has been linked to several significant physiological effects:

* Energy Expenditure and Obesity Management: Studies have shown that TLQP-21 increases energy expenditure (EE) and can prevent the early stages of diet-induced obesity.
