MHC CLASS I H-2KB HEAVY CHAIN COMPLEXED WITH BETA-2 MICROGLOBULIN AND SENDAI VIRUS NUCLEOPROTEIN

Structural highlights

2vab is a 3 chain structure with sequence from Lk3 transgenic mice and Sendai virus. This structure supersedes the now removed PDB entry 1vab. The February 2005 RCSB PDB Molecule of the Month feature on Major Histocompatibility Complex by David S. Goodsell is 10.2210/rcsb_pdb/mom_2005_2. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:	BETA-2-MICROGLOBULIN (LK3 transgenic mice)

Function

[HA1B_MOUSE] Involved in the presentation of foreign antigens to the immune system. [NCAP_SENDE] Encapsidates the genome in a ratio of one N per six ribonucleotides, protecting it from nucleases. The nucleocapsid (NC) has a helical structure with 13.07 N per turn. 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. [B2MG_MOUSE] Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.

Publication Abstract from PubMed

The x-ray structures of a murine MHC class I molecule (H-2Kb) were determined in complex with two different viral peptides, derived from the vesicular stomatitis virus nucleoprotein (52-59), VSV-8, and the Sendai virus nucleoprotein (324-332), SEV-9. The H-2Kb complexes were refined at 2.3 A for VSV-8 and 2.5 A for SEV-9. The structure of H-2Kb exhibits a high degree of similarity with human HLA class I, although the individual domains can have slightly altered dispositions. Both peptides bind in extended conformations with most of their surfaces buried in the H-2Kb binding groove. The nonamer peptide maintains the same amino- and carboxyl-terminal interactions as the octamer primarily by the insertion of a bulge in the center of an otherwise beta conformation. Most of the specific interactions are between side-chain atoms of H-2Kb and main-chain atoms of peptide. This binding scheme accounts in large part for the enormous diversity of peptide sequences that bind with high affinity to class I molecules. Small but significant conformational changes in H-2Kb are associated with peptide binding, and these synergistic movements may be an integral part of the T cell receptor recognition process.
