Genes affected

PTCRA (HGNC:21290): (pre T cell antigen receptor alpha) The protein encoded by this gene is a single-pass type I membrane protein that is found in immmature but not mature T-cells. 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]
