pt 161 peptide A small peptide antagonist of integrin alpha5beta1

Published October Oct 17, 2026 7:43 PM

When exploring advanced biochemical research, one frequently encounters the term pt 161 peptide, often conflated with various synthetic compounds in literature. It is essential to clarify that in scientific databases, the primary subject of interest is ATN-161, a well-documented five-amino acid peptide that serves as a focal point for researchers studying cell signaling and receptor dynamics.

The Biochemical Profile of ATN-161

ATN-161 is a non-RGD based integrin binding peptide derived from the synergy region of fibronectin. Its chemical structure, often noted as Ac-PHSCN-NH2, makes it a specialized tool for laboratory investigations. Unlike standard RGD motifs, this small peptide antagonist of integrin alpha5beta1 interacts specifically with the N-terminus of the beta-1 region, which is a critical area of focus for those analyzing angiogenesis and cellular migration.

As someone who tracks peptide research, I find the specificity of the PHSCN peptide (licensed as ATN-161) to be particularly fascinating. It acts as an alpha v beta 1 inhibitor and is recognized as a novel integrin alpha5beta1 antagonist. Because it selectively binds to and blocks the receptor for integrin, it has been a frequent subject in studies regarding the inhibition of tumor growth, angiogenesis, and metastasis.

E-E-A-T and Research Integrity

When reviewing data on The Integrin Binding Peptide, ATN-161, it is vital to rely on peer-reviewed literature and high-quality chemical suppliers. Many of the studies cited in academic repositories, such as PubMed, underscore the importance of purity and structural integrity in these compounds. Whether you are looking at the Bcl-2-like protein 11 142-161 or the SHBG141–161 peptide, the nomenclature can be confusing. However, ATN 161 is a α5β1 integrin receptor antagonist that remains distinct from other epitope markers.
