Gene Gene information from NCBI Gene database.
Entrez ID 51095
Gene name TRNA nucleotidyl transferase 1
Gene symbol TRNT1
Synonyms (NCBI Gene)
CCA1CGI-47MtCCARPEMSIFD
Chromosome 3
Chromosome location 3p26.2
Summary The protein encoded by this gene is a CCA-adding enzyme which belongs to the tRNA nucleotidyltransferase/poly(A) polymerase family. This essential enzyme functions by catalyzing the addition of the conserved nucleotide triplet CCA to the 3` terminus of tR
