Summaries for PTCRA Gene

Entrez Gene Summary for PTCRA Gene

  • 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]

GeneCards Summary for PTCRA Gene

PTCRA (Pre T-Cell Antigen Receptor Alpha) is a Protein Coding gene. Diseases associated with PTCRA include Granulomatous Orchitis and Shoulder Impingement Syndrome. Among its related pathways are Notch signaling pathway (Pathway Interaction Database) and C-MYB transcription factor network.

UniProtKB/Swiss-Prot for PTCRA Gene

  • The pre-T-cell receptor complex (composed of PTCRA, TCRB and the CD3 complex) regulates early T-cell development.
