MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygous inactivation of this gene results in lack of "N" nucleotide insertions at the junctions of immunoglobulin and T cell receptor V(D)J rearrangements. Forced expression of terminal deoxynucleotidyl transferase in fetal thymus leads to decreased gamma-delta T cell number. [provided by MGI curators]
