p21 peptide sequence p21 (CIP1/WAF1) protein

Published October Oct 17, 2026 6:05 PM

In the evolving field of synthetic compounds, the p21 peptide sequence has garnered significant attention from those interested in neuro-regenerative research. As someone who has spent considerable time exploring the landscape of experimental research compounds, I find the structural nuances of this molecule particularly fascinating. When we look at P21 peptide information, it is essential to distinguish between the various iterations, such as the P021 variant and the classic P21 peptide.

Structural Breakdown and Sequence

The core of the p21 peptide is often identified by its specific amino acid arrangement. A common sequence cited in literature is Ac-DGGLAG-NH2. This tetra-peptide is derived from the biologically active region of the human ciliary neurotrophic factor (CNTF). Interestingly, some formulations, often referred to as P21 peptide acetate, incorporate adamantane building blocks—specifically, the sequence DGGL-adamantane-G—to enhance stability and permeability.

Unlike the endogenous p21 (CIP1/WAF1) protein, which functions as a cyclin-dependent kinase inhibitor to regulate the cell cycle, the synthetic P21 compound is designed to mimic neurotrophic signaling pathways.

However, researchers must always prioritize source verification and purity. The P21 peptide is a synthetic peptide that requires careful handling to ensure its stability. Whether you are looking at the p21-IRS chimeric peptide or the standard neurotrophic sequence, the molecular weight (often cited around 578.3 g/mol for the basic form) is a standard parameter for confirming the identity of the substance.

Summary of Key Entities

* Sequence: Ac-DGGLAG-NH2 or DGGL-adamantane-G.

* Classification: Synthetic neurotrophic peptide derivative.

* Mechanism: Modulates cellular pathways related to neurogenesis and survival.

* LSI/Variations: P021, Peptide 6c, CNTF-derived peptide, ADAM-P21.

As you delve deeper into the P21 peptide, remember that this field is purely experimental. The p21 appears to have a small membrane binding domain at the C-terminus in its natural protein state, a feature that highlights the complexity of nomenclature in this domain. Always rely on peer-reviewed data and reputable laboratory standards when analyzing these compounds. By keeping these distinctions clear, you can better navigate the complex world of peptide research without conflating endogenous proteins with synthetic research analogs.
