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] Expression Biased expression in spleen (RPKM 20.9), lymph node (RPKM 16.3) and 4 other tissues See more Orthologs mouse all
