Background: FCRL4/FcRH4

FcRH4, also known as IRTA1 (immunoglobulin superfamily receptor translocation associated 1), is a member of the Ig superfamily. It shares sequence homology with the classical Fc receptors. FcRH4 is preferentially expressed in B cells and contains three potential ITIM motifs in its extracellular domain. The gene for FcRH4 is localized to the human chromosome Iq 21‑23 region, a hotspot for translocation events.
