Internalizing RGD (iRGD) peptides are a class of 9-amino acid cyclic peptides containing an RGD sequence, which undergo internalization as discussed below. The prototypic iRGD peptide, shown in the image on the right (sequence: CRGDKGPDC; CAS 1392278-76-0), was originally identified in an in vivo screening of phage display libraries in tumor-bearing mice.

Coarse-grained models are often implemented in the case of protein-peptide docking, as they frequently involve large-scale conformation transitions of the protein receptor. [7] [8] AutoDock is one of the computational tools frequently used to model the interactions between proteins and ligands during the drug discovery process. Although the ...
Each nonribosomal peptide synthetase can synthesize only one type of peptide. Nonribosomal peptides often have cyclic and/or branched structures, can contain non-proteinogenic amino acids including D-amino acids, carry modifications like N-methyl and N-formyl groups, or are glycosylated, acylated, halogenated, or hydroxylated.
Macromolecular docking is the computational modelling of the quaternary structure of complexes formed by two or more interacting biological macromolecules. Protein–protein complexes are the most commonly attempted targets of such modelling, followed by protein–nucleic acid complexes.
During the course of the docking process, the ligand and the protein adjust their conformation to achieve an overall "best-fit" and this kind of conformational adjustment resulting in the overall binding is referred to as "induced-fit". [5] Molecular docking research focuses on computationally simulating the molecular recognition process.
In eukaryotes, SRP binds to the signal sequence of a newly synthesized peptide as it emerges from the ribosome. [1] This binding leads to the slowing of protein synthesis known as "elongation arrest", a conserved function of SRP that facilitates the coupling of the protein translation and the protein translocation processes.

Docking glossary Receptor or host or lock The "receiving" molecule, most commonly a protein or other biopolymer. Ligand or guest or key The complementary partner molecule which binds to the receptor. Ligands are most often small molecules but could also be another biopolymer. Docking Computational simulation of a candidate ligand binding to a ...
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
