Gene Gene information from NCBI Gene database.
Entrez ID 171558
Gene name Pre T cell antigen receptor alpha
Gene symbol PTCRA
Synonyms (NCBI Gene)
IMD126PT-ALPHAPTA
Chromosome 6
Chromosome location 6p21.1
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 developme
