研究背景

機能:

Receptor for the Fc region of complexed or aggregated immunoglobulins gamma. Low affinity receptor. Involved in a variety of effector and regulatory functions such as phagocytosis of immune complexes and modulation of antibody production by B-cells. Binding to this receptor results in down-modulation of previous state of cell activation triggered via antigen receptors on B-cells (BCR), T-cells (TCR) or via another Fc receptor. Isoform IIB1 fails to mediate endocytosis or phagocytosis. Isoform IIB2 does not trigger phagocytosis.

PTMs:

Phosphorylated by the SRC-type Tyr-kinases LYN and BLK.

組織特異性:

Is the most broadly distributed Fc-gamma-receptor. Expressed in monocyte, neutrophils, macrophages, basophils, eosinophils, Langerhans cells, B-cells, platelets cells and placenta (endothelial cells). Not detected in natural killer cells.

サブユニット構造:

Interacts with INPP5D/SHIP1. Interacts with FGR. Interacts with LYN.

(Microbial infection) Isoform IIB1 interacts with measles virus protein N. Protein N is released in the blood following lysis of measles infected cells. This interaction presumably block inflammatory immune response.

タンパク質ファミリー:

Contains 1 copy of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is involved in modulation of cellular responses. The phosphorylated ITIM motif can bind the SH2 domain of several SH2-containing phosphatases.
