一些研究已经显示结合核心外的残基对结合和后续的T细胞识别的影响。在结合核心外部区域但在延伸的结合凹槽内的残基成为多肽侧翼残基(peptide-flanking residues,PFRs)。PFR对T细胞识别的重要性已经被研究。大家普遍认为这些侧面区域有助于T细胞对pMHC的识别。Arnold及其同事的研究表明某些T反应是完全依赖于在多肽P1和P11的残基。

Here we have studied the peptide length preferences of two rat MHC class I a molecules expressed in the TAP2-deficient mouse cell line RMA-S: RT1-A1 c , which carries unusual key residues at both ends of the groove, and RT1.A a which carries the canonical residues. Temperature-dependent...
(R = 0.5) is observed between peptide length and Cα LRMSD. By computing the Cα LRMSD we capture the accuracy of the backbone prediction. This is very meaningful information because a small error in the backbone has a bigger impact on the binding mode than a similar error in a ...
peptide tetramer starts with the MHC proteins, which are designed to bind a particular peptide antigen within their peptide-binding groove. For MHC class I, the peptide is typically 8-10 amino acids in length, while for MHC class II, the peptide is usually 13-25 amino acids long. This ...
The cellular proteome comprises ∼2 billion protein molecules, with an average length of 400 residues 10, 11; thus, if all proteins constitute a source for the class I pathway, there are 4 × 1011 peptides that could be presented, or 4 × 106 peptides per class I molecule. The ...
To avoid performance overestimation and model overfitting, training sets were split into 5 partitions for cross-validation purposes using the common motif algorithm (47) with a motif length of 8 amino acids for class I (corresponding to the shortest binding mode for class I peptides) and 9 amin...
the longer length of MHC class II peptides facilitates the formation of multiple contacts with the MHC molecule, enhancing the stability of the peptide-MHC complex. This length is instrumental in ensuring that the complex persistently communicates with T helper cells until the immune response is ach...
