Summaries for MICB Gene

Entrez Gene Summary for MICB Gene

  • This gene encodes a heavily glycosylated protein which is a ligand for the NKG2D type II receptor. Binding of the ligand activates the cytolytic response of natural killer (NK) cells, CD8 alphabeta T cells, and gammadelta T cells which express the receptor. This protein is stress-induced and is similar to MHC class I molecules; however, it does not associate with beta-2-microglobulin or bind peptides. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

GeneCards Summary for MICB Gene

MICB (MHC Class I Polypeptide-Related Sequence B) is a Protein Coding gene. Diseases associated with MICB include Dengue Shock Syndrome and Asymptomatic Dengue. Among its related pathways are Natural Killer Cell Receptors: Human Target Cell ?�� NK Cell Ligand-Receptor Interactions and Immune System. GO annotations related to this gene include antigen binding and natural killer cell lectin-like receptor binding. An important paralog of this gene is MICA.

UniProtKB/Swiss-Prot for MICB Gene

  • Seems to have no role in antigen presentation. Acts as a stress-induced self-antigen that is recognized by gamma delta T cells. Ligand for the KLRK1/NKG2D receptor. Binding to KLRK1 leads to cell lysis.

    Size:
    383 amino acids
    Molecular mass:
    42646 Da
    Quaternary structure:
    • Unlike classical MHC class I molecules, does not form a heterodimer with beta-2-microglobulin. Binds as a monomer to a KLRK1/NKG2D homodimer. KLRK1 forms a complex with HCST/DAP10 in which KLRK1 binds MICB while HCST acts as an adapter molecule which enables signal transduction. Receptor-ligand interaction induces clustering of both proteins in ordered structures called immune synapses and also leads to their intercellular transfer. This is associated with a reduction in the cytotoxicity of KLRK1-expressing cells. Binds to human cytomegalovirus glycoprotein UL16 which causes sequestration of MICB in the endoplasmic reticulum and increases resistance to KLRK1-mediated cytotoxicity.

Function for MICB Gene

Molecular function for MICB Gene

GENATLAS Biochemistry:
MHC class I,chain-related gene B,preferentially expressed in fibroblast and epithelial cell
UniProtKB/Swiss-Prot Function:
Seems to have no role in antigen presentation. Acts as a stress-induced self-antigen that is recognized by gamma delta T cells. Ligand for the KLRK1/NKG2D receptor. Binding to KLRK1 leads to cell lysis.
UniProtKB/Swiss-Prot Induction:
By heat shock, oxidative stress, retinoic acid, IFN-alpha and the DNA methyltransferase inhibitor 5-aza-2-deoxycytidine. Induction by IFN-alpha is impaired in patients with chronic hepatitis C virus infection. Down-regulated by human cytomegalovirus UL112 microRNA during viral infection which leads to decreased binding of KLRK1/NKG2D and reduced killing by natural killer cells.
