To study the expression of TBX5, a key gene during heart formation, full-length TBX5 cDNA was cloned from Wistar rat embryonic heart (GenBank Accession No. AY859491). The cDNA and predicted amino acid sequences were different from those previously reported in GenBank. The expression profile of TBX5 in rat tissues was studied by RT-PCR and Northern blot. TBX5 was expressed in many rat tissues as a single transcript, and the highest level of expression was found in the heart. For subcellular localization, TBX5 was expressed as an EGFP fusion protein in rat hepatocarcinoma cells. Results showed that TBX5 was nuclear. In addition, TBX5-GST fusion protein was obtained by prokaryotic expression. These findings provide a good basis for further identification of TBX5-related transcription factors and protein-protein interaction studies among each other.
