About FCER1A

Cytogenetic location: 1q23.2 Genomic coordinates (GRCh38): 1:159,283,575-159,308,202 (from NCBI)

This gene has 3 transcripts (splice variants), 196 orthologues and 17 paralogues. Broad expression in skin (RPKM 12.7), esophagus (RPKM 10.4) and 20 other tissues.

Summary

The immunoglobulin epsilon receptor (IgE receptor) is the initiator of the allergic response. When two or more high-affinity IgE receptors are brought together by allergen-bound IgE molecules, mediators such as histamine that are responsible for allergy symptoms are released. This receptor is comprised of an alpha subunit, a beta subunit, and two gamma subunits. The protein encoded by this gene represents the alpha subunit. [provided by RefSeq, Aug 2011]
