Disease

[B2MG_HUMAN] Defects in B2M are the cause of hypercatabolic hypoproteinemia (HYCATHYP) [MIM:241600]. Affected individuals show marked reduction in serum concentrations of immunoglobulin and albumin, probably due to rapid degradation.^[1] Note=Beta-2-microglobulin may adopt the fibrillar configuration of amyloid in certain pathologic states. The capacity to assemble into amyloid fibrils is concentration dependent. Persistently high beta(2)-microglobulin serum levels lead to amyloidosis in patients on long-term hemodialysis.^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8] ^[9] ^[10] ^[11] ^[12] ^[13] ^[14]

Function

[HA11_MOUSE] Involved in the presentation of foreign antigens to the immune system. [NCAP_PI1HW] Encapsidates the genome in a ratio of 1 N per 6 ribonucleotides, protecting it from nucleases. The nucleocapsid (NC) has a helical structure. The encapsidated genomic RNA is termed the NC and serves as template for transcription and replication. During replication, encapsidation by N is coupled to RNA synthesis and all replicative products are resistant to nucleases (By similarity). [B2MG_HUMAN] Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.

Publication Abstract from PubMed

In the absence of bound peptide ligands, major histocompatibility complex (MHC) class I molecules are unstable. In an attempt to determine the minimum requirement for peptide-dependent MHC class I stabilization, we have used short synthetic peptides derived from the Sendai virus nucleoprotein epitope (residues 324-332, 1FAPGNYPAL9) to promote its folding in vitro of H-2D(b). We found that H-2D(b) can be stabilized by the pentapeptide 5NYPAL9, which is equivalent to the C-terminal portion of the optimal nonapeptide and includes both the P5 and P9 anchor residues. We have crystallized the complex of the H-2D(b) molecule with the pentamer and determined the structure to show how a quasi-stable MHC class I molecule can be formed by occupancy of a single binding pocket in the peptide-binding groove.

The crystal structure of H-2D(b) complexed with a partial peptide epitope suggests a major histocompatibility complex class I assembly intermediate.,Glithero A, Tormo J, Doering K, Kojima M, Jones EY, Elliott T J Biol Chem. 2006 May 5;281(18):12699-704. Epub 2006 Feb 14. PMID:16478731^[15]
