Zinc phosphodiesterase ELAC protein 2, ElaC homolog protein 2, Heredity prostate cancer protein 2, Ribonuclease Z 2, RNase Z 2, tRNA 3 endonuclease 2, tRNase Z 2, ELAC2, HPC2
ELAC2 has a C-terminal domain with tRNA, processing endoribonuclease activity, which catalyzes the removal of the 3 trailer from precursor tRNAs. The protein also interacts with activated Smad family member 2 (Smad2) and its nuclear partner forkhead box H1 (also known as FAST-1), and reduced expression can suppress transforming growth factor-beta induced growth arrest.
