Along with TCRB and CD3 complex, the encoded protein forms the pre-T-cell receptor complex, which regulates early T-cell development. Four transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2011] Expression Biased expression in spleen (RPKM 1.2), lymph node (RPKM 0.8) and 5 other tissues See more Orthologs mouse all
