TRPT1, also known as tRNA 2-phosphotransferase 1, catalyzes the last step of tRNA splicing, the transfer of the splice junction 2-phosphate from ligated tRNA to NAD to produce ADP-ribose 1-2 cyclic phosphate. Recombinant protein corresponding to aa1-253 from human TRPT1, fused to His-tag at N-terminal expressed in E. coli.
