The mean alpha-MHC mRNA density per cell decreased by 50% (P < 0.01) after 2 days in culture and remained stable thereafter, whereas the relative amount of beta-MHC mRNA did not increase until day 5.

InterPro provides functional analysis of proteins by classifying them into families and predicting domains and important sites. We combine protein signatures from a number of member databases into a single searchable resource, capitalising on their individual strengths to produce a powerful integrated database and diagnostic tool.

The beta-2-microglobulin basically props the whole structure up by binding between the alpha 1 & alpha 2 domains and the alpha 3 The main function of MHC type 1 presentation of peptide to antigen to Tc cells. Consists of two polypeptide chain: Alpha chain– Alpha molecule is of 45 kDa. Each molecule consists of 30 amino acids.

Before their exposition on the cell surface, the MHC class II molecules react with endocytosed exogenous antigens, which are then presented to the T cells. The antigen-binding grove between MHC class II alpha and beta chain is open at both ends and is 15-24 amino acid residues long.

Both chains consist of two globular domains (N- and C-terminal), and a transmembrane segment to anchor them to the membrane [ (PUBMED:7612235) ]. A groove in … MHC-II ; alpha 1,2 and beta 1,2 domains. MHC-II ; present on all body cells. MHC-I ; antigen binding site is composed of alpha 1 and alpha 2 domains. MHC-II ; presents extracellular antigens from pathogens or other non-self proteins. MHC-I ; presents intracellular antigens from viruses or degraded self-proteins.

Beta-2 microglobulin: Similarly size in organisation to alpha-3. Bound non-covalently to alpha domain. MHC type 2 Direct transcriptional analyses of the alpha- and beta-MHC and cardiac and skeletal alpha-actin genes from cardiac nuclei were performed. In 23-24-day-old rats, significant levels of transcription were seen for alpha-MHC and for the sarcomeric alpha-actins.

In contrast, a positive correlation was observed between the antisense beta-RNA and the alpha-MHC pre-mRNA (P < 0.05). MHC-α is a 224 kDa protein composed of 1939 amino acids. The MYH6 gene is located on chromosome 14q12, approximately ~4kb downstream of the MYH7 gene encoding the other major cardiac muscle isoform of myosin heavy chain, MHC-β. MHC-β is a hexameric, asymmetric motor forming the bulk of the thick filament in cardiac muscle. MHC-β is composed of N-terminal globular heads (20 nm) that project laterally, and alpha helical tails (130 nm) that dimerize and multimerize into a coiled-coil motif to form the light meromyosin (LMM), thick filament rod. Figure 6 MHC class II molecules comprise two non-identical peptides (alpha and beta) which are non-covalently associated and traverse the plasma membrane with the N terminus to the outside of the cell. The domains closest to the membrane in each chain are structurally related to immunoglobulins.

alpha-MHC isogene expression was predominant in control myocytes (68% alpha-isoprotein and 60% alpha-iso-mRNA). In contrast, beta-MHC expression was equal to alpha-MHC or predominant after treatment with NE (51% beta MHC class 1 refers to one class of major histocompatibility complex molecules found on the surface of all nucleated cells in mammals. MHC class 1 molecule is composed of three alpha domains (alpha 1, alpha 2, and alpha 3) and a single beta domain. Alpha domains are encoded by the chromosome 6 while the beta domain is encoded by chromosome 11 MHC Class I molecules are composed of two nonidentical chains, long alpha chain, and one short beta chain. They are encoded by human leukocyte antigen genes (HLA) HLA-A, HLA-B, and HLA-C. Alpha chain is coded on the locus of MHC in chromosome 6 and beta chain is encoded on chromosome 15. MHC-klass II-molekyler har två identiska alfa- och beta-kedjor, vilka kodas av MHC-locus av kromosom 6.

Differences: 1. Class 2 is made up of 2 separate polypeptide chains (the alpha and beta chain) whereas class 1 is composed of a single chain= an alpha chain.

MHC I presentation and signaling is a global “alarm” system for the cells in the body. The Class I MHC molecule is made of 2 proteins- a three-domain alpha unit non-covalently bonded to beta-2 microglobulin. The amino acid sequence and shape of these subunits determines the shape of the binding groove and therefore what peptide can bind.

The cardiac-specific murine alpha myosin-heavy chain (Myh6, myosin, heavy polypeptide 6, cardiac muscle, alpha) promoter drives expression of cre in this transgenic strain.Breeding this mouse with another carrying loxP-flanked sequences results in the deletion of the flanked sequences in the offspring. Detailed analysis of eight overlapping MHC genomic clones shows that the alpha- and beta-MHC genes are organized in tandem and span 50 kilobases of the chromosome. The beta-MHC gene, predominantly expressed in late fetal life, is located 4 kilobases upstream from the alpha-MHC gene, predominantly expressed in the adult.
