Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Target Background

Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.
Gene References into Functions
  1. When no programmed delay interval was imposed, the beta2m-deficient mice acquired the task as fast as controls, suggesting that discrimination of left and right positions is not impaired by the total loss of hippocampal asymmetry. beta2m-deficient mice made fewer correct responses than control mice when variable delay was imposed, suggesting that the asymmetry of hippocampal circuitry plays an important role in working... PMID: 28039089
  2. The results show that, although other factors influence the fibril growth kinetics, a striking difference in the solubility of the proteins is a key determinant of the different amyloidogenicity of human B2M and mouse B2M. PMID: 26780548
  3. Use of shRNA against beta-2-microglobulin offers a simple and effective approach to minimize immunogenicity of the main cellular components of cardiac tissue constructs in non-syngeneic recipients. PMID: 25775354
  4. systemic B2M accumulation in aging blood promotes age-related cognitive dysfunction and impairs neurogenesis PMID: 26147761
  5. Because all forms of H-2K(b) are internalized but little beta2m-receptive heavy chain is present at the cell surface, it is likely that beta2m dissociation and recognition of the heavy chain for lysosomal degradation take place in an endocytic compartment. PMID: 25782992
  6. We report a novel dichotomous role of beta2m and CD1d, whereby these molecules differently regulate autoimmunity against phospholipid versus non-phospholipid autoantigens. PMID: 23531237
  7. The goal of the present work was to study peculiarities in functioning of proteasomes and associated signaling pathways along with evaluation of NeuN and gFAP expression in different sections of the brain in mice. PMID: 24237146
  8. MHC I and b2m genes are both expressed in in human as well as mice during the developmental stages of cerebellar cortex PMID: 24272393
  9. Knocking out beta 2 microglobulin abolishes NMDAR-dependent LTD in area CA1 of adult mouse hippocampus and is accompanied by memory deficits. MHC class I expression could be an unexpected cause of disrupted synaptic plasticity and cognitive deficits. PMID: 23959708
  10. This study demonistrated that Deletion of beta-2-microglobulin ameliorates spinal cord lesion load and promotes recovery of brainstem NAA levels in a murine model of multiple sclerosis PMID: 22335434
  11. Data show that tapasin expression is enhanced by beta 2-microglobulin via both transcriptional and post-transcriptional mechanisms. PMID: 23089196
  12. This gene is known to be important for immune responses and may potentially regulate alcohol consumption. PMID: 21309947
  13. Data show that NK subsets bearing Ly49s, which bind "self-MHC" were found to be the dominant subset responsible for beta2m(-/-) BMC rejection. PMID: 22184406
  14. Skin graft rejection induced by B2m-derived minor transplantation antigens involves Th2-dependent eosinophilic rejection, IFN-gamma dependent mechanisms, and Fas-Fas ligand interactions. PMID: 12077281
  15. beta-2 microglobulin knockout-anti-asialoGM1 mice exhibit improved hemodynamics and cardiac contractile function after cecal ligation and puncture that may account, in part, for survival benefit PMID: 14630624
  16. Rag1 deficiency in Hfe knock-out mice leads to heightened iron overload, mainly in the liver, whereas the heart and pancreas are relatively spared compared with beta2mRag1(-/-) mice. PMID: 14656877
  17. Beta 2 microglobulin deficient mice react normally to endotoxin and their hepatocytes react normally to IL-6. PMID: 15192150
  18. Results show that a seven-residue segment of human beta2-microglobulin (beta2M), not found in mouse beta2M, is sufficient to convert beta2M to the amyloid state, and that specific residue interactions are crucial to the conversion. PMID: 15249659
  19. Knockout mice represent an instructive model of spontaneous iron overload resembling genetic hemochromatosis. PMID: 15315790

  21. The results suggested that beta2m as well as TAP was necessary for the transportation of blastocyst MHC from endoplasmic reticulum to cell surfaces through the Golgi apparatus, similar to other MHC class I molecules. PMID: 15896332
  22. thermodynamic stabilities of the beta2m variants PMID: 16229893
