Question

Quizplus · Accepted Answer

FcF1F1F1S1F1F1F10RIIB (CD32)is a low-affinity IgG receptor expressed on B lymphocytes.When antigen-IgG complexes simultaneously bind to membrane Ig and to FcF1F1F1S1F1F1F10RIIB,phosphatases activated by FcF1F1F1S1F1F1F10RIIB block activating signals from the B cell antigen receptor complex.
