MICB also known as MHC class I polypeptide-related sequence B is a protein with a molecular weight of around 42 kDa. It anchors on cell surfaces and is widely expressed in epithelial cells fibroblasts and monocytes. MICB surfaces on stressed cells but remains minimal in normal conditions indicating its involvement in cell stress response. It is an activating ligand for NKG2D receptor on natural killer (NK) cells and certain T cells playing a major role in immune surveillance.
Biological function summary
MICB contributes to immune system functioning by presenting stress-induced antigens to immune cells. It does not belong to a complex but engages in interactions critical for activating cytotoxic responses. By binding to the NKG2D receptor it helps activate NK cells and certain T cell subsets which results in the elimination of damaged or transformed cells. This immune activation is important for the surveillance against cancer and infected cells maintaining tissue homeostasis.
Pathways
MICB plays a role in the stress-induced NKG2D signaling pathway and is involved in the immune response pathway. It cooperates with proteins such as NKG2D and MICA another ligand of the NKG2D receptor to initiate immune cell-mediated cytotoxicity. These pathways activate NK cells and CD8+ T cells important for removing stressed or altered cells thereby influencing the body's defense mechanisms.
MICB has connections to cancer and autoimmune disorders. Aberrant expression of MICB appears in tumors affecting tumor immune evasion and associates with autoimmune diseases influencing immune tolerance. Dysregulation of MICB activity can affect interactions with proteins like NKG2D altering immune responses and contributing to disease progression. Therefore understanding MICB's role is critical for developing therapeutic interventions targeting immune-related diseases.
