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.
