Rabbit Anti-MHC class I/FITC Conjugated antibody
background:
MHC Class I molecules play a central role in the immune system by presenting peptides derived from the endoplasmic reticulum lumen. MHC class I antigens are heterodimers consisting of one alpha chain (44kDa) with beta 2 microglobulin (11.5 kDa). The antigen is expressed by all somatic cells at varying levels. MHC Class I molecules are expressed on most nucleated cells where they present endogenously synthesized antigenic peptides to CD8+ T lymphocytes, which are usually cytotoxic T cells. Fibroblasts or neurons however only show a low level of antigen.
Function:
Involved in the presentation of foreign antigens to the immune system.
Subunit:
Heterodimer of an alpha chain and a beta chain (beta-2-microglobulin). Interacts with human herpesvirus 8 MIR1 protein (By similarity).
Subcellular Location:
Cell Membrane; Type I membrane protein.
Post-translational modifications:
Polyubiquitinated in a post ER compartment by interaction with human herpesvirus 8 MIR1 protein. This targets the protein for rapid degradation via the ubiquitin system (By similarity).
Similarity:
Belongs to the MHC class I family.
Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
