My analysis of various studies indicates that this sequence was originally isolated through phage display library screening. The primary mechanism of action is its ability to functionally disrupt the interaction between VEGF and the KDR receptor. By occupying this specific binding site, the peptide acts as a competitive antagonist.
From a technical standpoint, the K237 peptide is typically produced via solid-phase peptide synthesis (SPPS), a process that ensures high purity and consistency for laboratory applications. This level of precision is critical when the goal is to bind to the KDR receptors with the specificity required for experimental molecular probes.
