Summaries for DNTT Gene

Entrez Gene Summary for DNTT Gene

  • This gene is a member of the DNA polymerase type-X family and encodes a template-independent DNA polymerase that catalyzes the addition of deoxynucleotides to the 3'-hydroxyl terminus of oligonucleotide primers. In vivo, the encoded protein is expressed in a restricted population of normal and malignant pre-B and pre-T lymphocytes during early differentiation, where it generates antigen receptor diversity by synthesizing non-germ line elements (N-regions) at the junctions of rearranged Ig heavy chain and T cell receptor gene segments. Alternatively spliced transcript variants encoding different isoforms of this gene have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for DNTT Gene

DNTT (DNA Nucleotidylexotransferase) is a Protein Coding gene. Diseases associated with DNTT include Lymphoblastic Lymphoma and Acute Leukemia. Among its related pathways are DNA Double-Strand Break Repair and Hematopoietic cell lineage. GO annotations related to this gene include DNA-directed DNA polymerase activity and DNA polymerase activity. An important paralog of this gene is POLB.

UniProtKB/Swiss-Prot for DNTT Gene

  • Template-independent DNA polymerase which catalyzes the random addition of deoxynucleoside 5-triphosphate to the 3-end of a DNA initiator. One of the in vivo functions of this enzyme is the addition of nucleotides at the junction (N region) of rearranged Ig heavy chain and T-cell receptor gene segments during the maturation of B- and T-cells.
