Two upstream elements activate transcription of a major histocompatibility complex class I gene in vitro.
Expression of major histocompatibility complex (MHC) class I genes exhibits unique tissue and developmental specificity. In an effort to study molecular mechanisms of MHC class I gene regulation, an in vitro transcription system has been established. In B cell nuclear extracts a template DNA containing the mouse H-2Ld promoter sequence accurately directed RNA polymerase II-dependent transcripti...
متن کاملFrequency of Major Histocompatibility Antigens Class I in Mazandaran Province
Background and purpose: Major histocompatibility antigens are the most polymorphic components of the immune system. The purpose of this study was to determine the frequency of human leukocyte antigens (HLA) in a population in Mazandaran province, Iran. Materials and methods: In a cross sectional study, peripheral blood samples were obtained from 550 people in Immunogenetics Research Center af...
متن کاملMajor Histocompatibility Complex, Class I, B
Description The genes of the Human Leukocyte Antigen (HLA) system reside on chromosome 6, and code for cellsurface proteins that play a crucial role in the presentation of endogenic peptides to effector cells of the immune system. The HLA Class I protein molecule is a heterodimer, made up of two chains; a heavy one and a light one (beta 2 microglobulin). The HLA-B gene is one of the three HLA C...
متن کاملRepetitive elements in the major histocompatibility complex (MHC) class I region of a teleost, medaka: identification of novel transposable elements
The repetitive elements of medaka (Oryzias latipes) are poorly characterized in spite of recent rapid progress in the medaka genome analysis. Here we report the characterization of the repetitive elements in the major histocompatibility complex (MHC) class I region, which spans about 400 kb and is one of the best characterized regions of the medaka genome. Microsatellite, low complexity regions...
متن کاملTwo distinct proteolytic processes in the generation of a major histocompatibility complex class I-presented peptide.
Although cellular proteins degraded by proteasomes are the source of most antigenic peptides presented on major histocompatibility complex class I molecules, it is unknown whether the eight- to nine-residue peptides that fit in the binding groove of class I molecules are directly produced by proteasomes alone in vivo. If the eight-residue peptide SIINFEKL from chicken ovalbumin is extended by o...
