Background: FCRLA

FCRLA (Fc Receptor-Like A; also known as FcRX, FcRL1 and Fc receptor Homolog Expressed in B cells/FREB) is a 40-44 kDa intracellular member of the Fc gamma RI class, FcR family, Immunoglobulin Superfamily of molecules. Initially, it is associated with germinal center B cells that are undergoing somatic hypermutation and class-switch recombination. Now, it is believed that all B cells (but not CD38⁺ plasma cells) are also FCRLA⁺. FCRLA is suggested to act as an ER chaperone during antibody maturation, and is known to bind to IgM, IgA, and IgG prior to their secretion. Human FCRLA is synthesized as a 359 amino acid (aa) precursor that contains a 27 aa signal sequence plus a mature region that contains two C2-type Ig-like domains (aa 70-159 and 170-257), and a C-terminal poly-Proline region (aa 269-315). Although there is no traditional ER retention signal, a viable substitute is assumed to exist in the N-terminus of the mature molecule. FCLRA is believed to exist naturally as a monomer; however, disulfide-linkage can occur during experimental manipulation. At least eight potential isoform variants have been reported. It is unclear if, or how frequently they are expressed. One utilizes an alternative start site 17 aa upstream of the standard site, a second contains a six aa insertion after Ala28, and a third possessess an four aa substitution for aa 29-166. Five show single block deletions; in random order, they involve aa 78-166, 27-166, 78-261, 21‑261 and 167-26. Over aa 270-359, human FCLRA shares 55% aa sequence identity with mouse FCRLA.
