Research/Clinical Interest
B Lymphocyte Development and Function
B Lymphocyte Development and Function The long term goal of our studies is to understand the normal progression of the multipotential hemopoietic stem cell as it commits to development along the B cell lineage, undergoing the changes in phenotype and genotype that are characteristic of B cells. Intracellular Fc receptor-related proteins We have identified FCRLA as a new member of the larger Fc receptor (FcR) and FcR-like (FCRL) gene family of humans and mice. Among hemopoietic cells, FCRLA expression is restricted to B cells. In humans, FCRLA is preferentially expressed by germinal center B cells but its expression in the mouse has not yet been defined. The conventional FcR and the FcRL molecules are nearly all transmembrane proteins, and all of them have extracellular glycoprotein domains for ligand binding. In striking contrast, FCRLA is an intracellular protein. It lacks N-linked glycosylation sites and a transmembrane region, but contains a signal sequence common to proteins targeted to the endoplasmic reticulum (ER). Our data now clearly indicate a role for FCRLA as a resident ER protein that associates with immunoglobulin in this organelle. Moreover, analysis of FCRLA expression in the Ramos IgM B cell line, which produces both the membrane (m) and secretory (s) isoforms of μ heavy chain, indicates that FCRLA preferentially associates with μs. The unique features and restricted cellular distribution of FCRLA suggest its importance in the metabolism of Ig in B cells and in normal immune system function. Definition of the composition and function of the Ig-FCRLA complex is a major goal of our studies. These functions could include aiding Ig folding, facilitating Ig assembly, regulating Ig transport, and/or monitoring the degradation of incompletely processed Ig molecules. FCRLA may play an essential role in the intracellular quality control system that ensures the correct production of antibodies. Moreover, its preferential expression in human germinal center B cells, where B cell proliferation, antibody class switching, and mutation of antibody variable region genes occurs, suggests that defects in FCRLA expression may lead to autoimmunity or immunodeficiency diseases. The mb-1 gene During a subtractive cDNA screen for developmentally regulated genes in B cells, we isolated the human version of mb-1. This gene encodes Igα (CD79a), a transmembrane glycoprotein that forms a covalent heterodimer with Ig (CD79b) and associates noncovalently with surface immunoglobulin (sIg) on B cells to form the B cell antigen receptor. The Igα/ chains are essential chaperones for cell surface expression of the BCR and are the signal transducing components of the receptor. The acronym mb-1 derived from "mouse B-cell-specific gene number 1", the name coined by Sakaguchi and colleagues who first cloned the gene in mice. The human mb-1 gene is also expressed predominantly in B cells, but we observed low level mRNA expression in certain T cell lines. We have recently extended this analysis to normal cells and find that mb-1 mRNA is also expressed in normal human T cells. Intriguingly, the mb-1 gene product, Igα, is found in some T cell lines but not in normal T lymphocytes. This finding implies that translation of mb-1 is regulated differently in T and B cells, and that the translational regulation is defective in transformed T cells. The human mb-1 mRNA contains a region of ~ 100 nucleotides in the 3' untranslated region that is highly conserved (>90%) in mouse and bovine mb-1. We hypothesize that this conserved region is important in the translational regulation of mb-1 expression.
