Receptors for the Fc region of IgG (Fc γ R) are members of the Ig superfamily that function in the activation or inhibition of immune responses.
Three classes of human Fc γ Rs: RI (CD64), RII (CD32), and RIII (CD16), which generate multiple isoforms, are recognized.
There are three genes for human Fcγ RII /CD32 (A, B, and C) and one for mouse Fcγ RII B (CD32B).
CD32 is a low affinity receptor for IgG.
Low affinity immunoglobulin gamma Fc region receptor II-b (FCGR2B) is also known as CD32b, FCG2, IGFR2.
CD32B is expressed on B cells and myeloid dendritic cells.
Ligation of CD32B on B cells downregulates antibody production and may, in some circumstances, promote apoptosis.
Co-ligation of CD32B on dendritic cells inhibits maturation and blocks cell activation.
CD32B may also be a target for monoclonal antibody therapy for malignancies.
特徴
This protein carries an Avi tag (Avitag) at the C-terminus, followed by a polyhistidine tag.
The protein has a calculated MW of 24.0 kDa.
The protein migrates as 38-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
