Descriptions

Retinoic-acid-inducible gene-I (RIG-I; also called DDX58) is a cytosolic viral RNA receptor that interacts with MAVS to induce type I interferon-mediated host protective innate immunity against viral infection. The amino-terminal caspase recruitment domains (CARDs) of RIG-I undergo robust ubiquitination induced by TRIM25 that is involved in cell proliferation and antiviral activity in mammalian cells. In resting cells, RIG-I RD (a C-terminal repressor domain) represses its CARDs signaling. After viral infection, RIG-I RD recognizes 5’-triphosphate double-stranded RNA (dsRNA), which results in a conformational change in the RIG-I protein.

7 GO annotations of cellular component

Name Definition
actin cytoskeleton The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes.
bicellular tight junction An occluding cell-cell junction that is composed of a branching network of sealing strands that completely encircles the apical end of each cell in an epithelial sheet; the outer leaflets of the two interacting plasma membranes are seen to be tightly apposed where sealing strands are present. Each sealing strand is composed of a long row of transmembrane adhesion proteins embedded in each of the two interacting plasma membranes.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
ribonucleoprotein complex A macromolecular complex that contains both RNA and protein molecules.
ruffle membrane The portion of the plasma membrane surrounding a ruffle.
