| The protein encoded by this gene has a C-terminal domain with tRNA 3&8242, 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. Mutations in this gene result in an increased risk of prostate cancer. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009],catalytic activity:Endonucleolytic cleavage of RNA, removing extra 3 nucleotides from tRNA precursor, generating 3 termini of tRNAs. A 3-hydroxy group is left at the tRNA terminus and a 5-phosphoryl group is left at the trailer molecule.,cofactor:Zinc.,disease:Defects in ELAC2 are involved in prostate cancer (CaP) [MIM:176807].,function:Zinc phosphodiesterase, which displays some tRNA 3-processing endonuclease activity. Probably involved in tRNA maturation, by removing a 3-trailer from precursor tRNA.,similarity:Belongs to the RNase Z family.,subunit:Homodimer.,tissue specificity:Widely expressed. Highly expressed in heart, placenta, liver, skeletal muscle, kidney, pancreas, testis and ovary. Weakly expressed in brain, lung, spleen, thymus, prostate, small intestine, colon and leukocytes., |
