CD307e (FcRL5) Antibody, anti-human, FITC, REAfinity™

01MT03272

Clone REA391 recognizes the human CD307e antigen, a 106 kDa single-pass type I membrane protein also known as Fc receptor-like protein 5 (FcRL5) or immune receptor translocation-associated protein 2 (IRTA2). CD307e possesses a cytoplasmic tail with inhibitory ITIM phosphorylation signaling motifs and was found to inhibit B cell antigen receptor signaling by recruiting SHP1 to two ITIM motifs upon B cell antigen receptor co-stimulation, resulting in diminished calcium influx and protein tyrosine phosphorylation. Co-stimulation of CD307e and the B cell antigen receptor promotes proliferation and
