Background: FCRL4/FcRH4

Fc receptor-like 4 (FCRL4), also known as FcRH4, IFGP2 and IRTA1, is a member of the Ig superfamily transmembrane protein, which is preferentially expressed in B cells and contains immunoreceptor tyrosine-based inhibitory motifs (ITIMs) (1). Mature human FCRL4 consists of a 368 amino acid (aa) extracellular domain (ECD) with four Ig-like C2-type domains, a 21 aa transmembrane segment, and a 107 aa cytoplasmic domain with three ITIM-like motifs. FCRL4 is closely related to FC gammaRIIB (2, 3) and shows high homology to Fc receptors (4). In cellular binding assays, FCRL4 bound to IgA efficiently (5). The FCRL4 gene is localized in the human chromosome 1q21-23 region, a hotspot for translocation events (3). The B cells expressing FCRL4 participate in the autoimmune response in rheumatoid arthritis patients (6).
