Cloning, characterization and expression of the polypeptide release factor gene, eRF1, of Blepharisma japonicum

Cloning, characterization and expression of the polypeptide release factor gene, eRF1, of... The polypeptide release factor gene, eRF1, of Blepharisma japonicum (Bj-eRF1) was cloned and sequenced. Its coding region was 1314 base pairs and encodes a protein of 437 amino acids. The cloned gene was expressed in Escherichia coli and the recombinant Bj-eRF1 polypeptide was purified by Ni2+-nitrilotriacetic acid agarose and Superose12 chromatography. Pull-down analysis showed that the recombinant Bj-eRF1 interacts with the heterologously-expressed release factor, eRF3C, of Euplotes octocarinatus. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Biotechnology Letters Springer Journals

Abstract

The polypeptide release factor gene, eRF1, of Blepharisma japonicum (Bj-eRF1) was cloned and sequenced. Its coding region was 1314 base pairs and encodes a protein of 437 amino acids. The cloned gene was expressed in Escherichia coli and the recombinant Bj-eRF1 polypeptide was purified by Ni2+-nitrilotriacetic acid agarose and Superose12 chromatography. Pull-down analysis showed that the recombinant Bj-eRF1 interacts with the heterologously-expressed release factor, eRF3C, of Euplotes octocarinatus.
