Also Known as CCA1; RPEM; SIFD; MtCCA; CGI-47

Species: Homo sapiens

Gene Type: protein coding
Gene ID: 51095

About TRNT1

Cytogenetic location: 3p26.2 Genomic coordinates (GRCh38): 3:3,126,940-3,153,435 (from NCBI)

This gene has 31 transcripts (splice variants), 203 orthologues and is associated with 5 phenotypes. Ubiquitous expression in prostate (RPKM 8.6), testis (RPKM 7.5) and 25 other tissues.

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 tRNA molecules. Mutations in this gene result in sideroblastic anemia with B-cell immunodeficiency, periodic fevers, and developmental delay. Alternative splicing results in multiple transcript variants.
