Fusion genes
(updated 2015)
ELAC2 (17p12) / COX10 (17p12)
Note There is a human paralog of this gene on chromosome 18 called ELAC1 that is homologous to the C-terminal half of ELAC2.


Note Ubiquitously expressed in a variety of tissues, tumors and developmental stages.
Description The genomic size of ELAC2 gene is about 25.6 kb representing a mRNA of 2966 bp with 26 exons.
Transcription There is no evidence of alternative splicing of the transcript.
Pseudogene No known pseudogenes.


Description ELAC2 gene encodes a protein of 826 amino acids. Orthologs are found in Eukaryotes including M. musculus, R. norvegicus, C. elegans, D. melanogaster, S. cerevisiae, S. pombe and A. thaliana.
Expression Not determined.
Localisation Not determined. But is implicated in nucleus upon overexpression in cell lines. Yeast ortholog (TRZ1p) is detected in cytosol, nucleus and mitochondria via large-scale analysis with GFP tagged gene product.
Function ELAC2 has tRNA processing activity as detected by in vitro biochemistry assays. The N-terminus of ELAC2 is required for the Rnase 65 activity. The C-terminus (481-826 aa) of ELAC2, which is homologous to ELAC1, possesses tRNA 3' processing endoribonuclease acitivity (tRNaseZ). Overexpressed ELAC2 binds gamma-tubulin complex and is involved in cell cycle regulation. ELAC2 has also been shown to potentiate TGF-beta-induced growth arrest of prostate cells via over-expression upon transfection and down-regulation via siRNA.


Germinal One pedigree-specific insertion/frameshift, 1641insG, resulting in frameshift after L547, and leading to termination after the miscoding of 67 residues. Four missense variants, S217L, A541T, E622V and R781H.
Somatic Not determined.

Implicated in

Entity Prostate Cancer
Note TGF-beta signaling mediated growth arrest via physical interactions with Smad2 / Smad3 and FAST-1, and potentiation of Smad2-driven (ARE)2-Luciferease reporter activity. Also implicated in RNA processing.
Disease Hereditary prostate cancer and sporadic prostate cancer.
