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

[1A02_HUMAN] Involved in the presentation of foreign antigens to the immune system. [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

The three-dimensional structure of a human alphabeta T cell receptor (TCR), B7, bound to the HLA-A2 molecule/HTLV-1 Tax peptide complex was determined by x-ray crystallography. Although different from the A6 TCR, previously studied, in 16 of the 17 residues that contact HLA-A2/Tax, the B7 TCR binds in a similar diagonal manner, only slightly tipped and rotated, relative to the A6 TCR. The structure explains data from functional assays on the specificity differences between the B7 and A6 TCRs for agonist, partial agonist, and null peptides. The existence of a structurally similar diagonal binding mode for TCRs favors mechanisms based on the formation of geometrically defined supramolecular assemblies for initiating signaling.

Two human T cell receptors bind in a similar diagonal mode to the HLA-A2/Tax peptide complex using different TCR amino acids.,Ding YH, Smith KJ, Garboczi DN, Utz U, Biddison WE, Wiley DC Immunity. 1998 Apr;8(4):403-11. PMID:9586631^[15]
