{"symbol":"FCER2","synonyms":["IGEBF","CLEC4J","CD23","FCE2","BLAST-2","CD23A"],"name":"Fc fragment of IgE, low affinity II, receptor for (CD23)","description":"The protein encoded by this gene is a B-cell specific antigen, and a low-affinity receptor for IgE. It has essential roles in B cell growth and differentiation, and the regulation of IgE production. This protein also exists as a soluble secreted form, then functioning as a potent mitogenic growth factor. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Jul 2011]","ncbiEntrezGeneId":2208,"ncbiEntrezGeneUrl":"http://www.ncbi.nlm.nih.gov/gene/2208","proteins":[{"symbol":"FCER2_HUMAN","href":"/api/1.0/protein/FCER2_HUMAN"}],"hgncRootFamilies":[{"name":"CD molecules (CD)","href":"/api/1.0/gene_family/CD+molecules+%28CD%29"},{"name":"C-type lectin domain family (CLEC)","href":"/api/1.0/gene_family/C-type+lectin+domain+family+%28CLEC%29"}]}
