Genetic Algorithm Managed Peptide Mutant Screening: Optimizing Peptide Ligands for Targeted Receptor Binding

screening phage display library for isolation of human colon cancer cell-binding peptide ligands

objective: recently, phage display libraries have received enormous attention for identification and isolation of pharmaceutical molecules with diagnostic and therapeutic properties. peptide libraries are known as one of the most important and widely used types of phage display libraries. in the current study, we aimed to screen the ph.d.tm-7 phage display peptide library through biopanning for...

Differential binding domains of peptide and non-peptide ligands in the cloned rat kappa opioid receptor.

This study was to identify specific regions in kappa opioid receptors that accounted for binding selectivity of kappa ligands. Six chimeric mu/kappa receptors were constructed from cloned rat kappa and mu opioid receptors and transiently expressed in COS-1 cells. All six chimeric mu/kappa receptors bound [3H] diprenorphine with high affinities, indicating that these chimeras retain opioid recep...

Differential activation of formyl peptide receptor signaling by peptide ligands.

Formyl peptide receptor (FPR) and formyl peptide receptor like 1 (FPRL1) play important roles in inflammation and immunity. Stimulation of FPR and FPRL1 initiates a cascade of signaling events, leading to activation of various phagocyte responses, including chemotaxis, superoxide generation, and exocytosis. Trp-Lys-Tyr-Met-Val-d-Met-NH2 (WKYMVm) is a synthetic peptide that binds to and activate...

Exploring Protein-Peptide Binding Specificity through Computational Peptide Screening

The binding of short disordered peptide stretches to globular protein domains is important for a wide range of cellular processes, including signal transduction, protein transport, and immune response. The often promiscuous nature of these interactions and the conformational flexibility of the peptide chain, sometimes even when bound, make the binding specificity of this type of protein interac...
