Publication Abstract from PubMed

T cell receptor (TCR) binding degeneracy lies at the heart of several physiological and pathological phenomena, yet its structural basis is poorly understood. We determined the crystal structure of a complex involving the BM3.3 TCR and an octapeptide (VSV8) bound to the H-2K(b) major histocompatibility complex molecule at a 2.7 A resolution, and compared it with the BM3.3 TCR bound to the H-2K(b) molecule loaded with a peptide that has no primary sequence identity with VSV8. Comparison of these structures showed that the BM3.3 TCR complementarity-determining region (CDR) 3alpha could undergo rearrangements to adapt to structurally different peptide residues. Therefore, CDR3 loop flexibility helps explain TCR binding cross-reactivity.

CDR3 loop flexibility contributes to the degeneracy of TCR recognition.,Reiser JB, Darnault C, Gregoire C, Mosser T, Mazza G, Kearney A, van der Merwe PA, Fontecilla-Camps JC, Housset D, Malissen B Nat Immunol. 2003 Mar;4(3):241-7. Epub 2003 Feb 3. PMID:12563259^[1]

-[[http://www.uniprot.org/uniprot/NCAP_VSIVG NCAP_VSIVG]] Encapsidates the genome in a ratio of one N per nine ribonucleotides, protecting it from nucleases. The encapsidated genomic RNA is termed the NC and serves as template for transcription and replication. Replication is dependent on intracellular concentration of newly synthesized N, termed N(0), which corresponds to the protein not associated with RNA. In contrast, when associated with RNA, it is termed N. During replication, encapsidation by N(0) is coupled to RNA synthesis and all replicative products are resistant to nucleases (By similarity).
