Peptide E in Cellular and Molecular Interactions

The interactions of Peptide E extend to cellular signaling and immune regulation作者：SN Dean·2021·被引用次数：110—We report apeptide generation framework, PepVAE, based around variational autoencoder (VAE) and antimicrobial activity prediction models for designing novel .... It plays a role in the presentation of self-peptides by HLA-E, a non-classical MHC class Ib molecule. These HLA-E/peptide complexes interact with natural killer (NK) cell receptors like NKG2A/CD94, thereby regulating NK cell-mediated cytotoxicity and contributing to tissue homeostasis. This interaction is crucial for immune surveillance and responselip case. In other biological contexts, peptides, in general, are recognized for their suitability as targeting moieties due to their small size, excellent cell permeability, and ease of production, making them valuable in areas like tumor-specific antigen targeting.
