FCRLA: FCRLA Protein | FCRLA Antibody

FCRLA Gene family

FCRLA Background

Fc receptor-like A (FCRLA) is a unique member of a family of Fc receptor like-molecules that lacks a transmembrane region and is an ER-resident protein. In mice and humans, FCRLA has been known as a B cell specific protein. FCRLA is homologous to receptors for the Fc portion of IgG (FcgammaR) and is located in the same region of human chromosome one, but has several unusual and unique features. It is a soluble resident ER protein retained in this organelle by unknown mechanisms involving the N-terminal domain, a disordered domain with three Cys residues in close proximity in the human protein. Unlike the FcgammaRs, FCRLA is not glycosylated and has no transmembrane region. High expression of FCRLA in subset(s) of terminally differentiated B-cells suggests that, being an ER protein, FCRLA may participate in the regulation of immunoglobulin assembly and secretion.

FCRLA protein function

May be implicated in B-cell differentiation and lymphomagenesis. {ECO:0000269|PubMed:11754007, ECO:0000269|PubMed:11891275}.

FCRLA protein expression

Tissue specificity

Expressed specifically in primary and secondary lymphoid tissues like lymph node, spleen and tonsil. Specifically expressed in B-cells with a high level in normal germinal center B-cells, centroblasts and in a subset of diffuse large B-cell lymphomas. Highly expressed in bone marrow B-cells and weakly in earlier B lineage cells. Expressed in pre-germinal and germinal center B-cells in secondary lymphoid tissues. Also expressed in melanoma and melanocytes.
