== Function Summary ==
* **Entrez Summary**: 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].
* **UniProt Summary**: The pre-T-cell receptor complex (composed of PTCRA, TCRB and the CD3 complex) regulates early T-cell development. {ECO:0000250}.
