Species TM AA Chromosomal Location Gene Symbol Gene Name Reference
Human 4 244 11q12.1 MS4A2 membrane spanning 4-domains A2

Gene and Protein Information Comments
The human MS4A2 gene produces two protein isoforms: isoform 1 (244aa) that traffics to the cytoplasmic membrane and isoform 3 (199aa) that triffics preferentially to the nuclear membrane. Four mouse protein isoforms are predicted.

Immunopharmacology Comments
The protein product of the MS4A2 gene is the β subunit of the FCεRI. It has commonly known as FCER1B. The IgE-receptor (FCεRI), is a tetramer composed of an α, β, and 2 disulfide-linked γ chains expressed on the surface of mast cells and basophils that is crucial for mediating the allergic response. It has been suggested that cytoplasmic FCER1B that is not associated with FCεRI complexes may act as a negative regulator of the signalling pathway to degranulation by sequestering important signalling partners such as the Lyn tyrosine kinase [1].
