CC -!- FUNCTION: Template-independent DNA polymerase which catalyzes the CC random addition of deoxynucleoside 5'-triphosphate to the 3'-end CC of a DNA initiator. One of the in vivo functions of this enzyme is CC the addition of nucleotides at the junction (N region) of CC rearranged Ig heavy chain and T-cell receptor gene segments during CC the maturation of B- and T-cells. CC -!- CATALYTIC ACTIVITY: Deoxynucleoside triphosphate + DNA(n) = CC diphosphate + DNA(n+1). CC -!- COFACTOR: Magnesium. CC -!- SUBUNIT: Interacts with PRP19 and TDIF1 (By similarity). CC -!- SUBCELLULAR LOCATION: Isoform TDT-S: Nucleus. Isoform TDT-L: CC Cytoplasm. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=TDT-L; Synonyms=TDT-Large, TdtL; CC IsoId=P09838-1; Sequence=Displayed; CC Note=Inactivated at physiological temperature but is stable at CC lower temperatures; CC Name=TDT-S; Synonyms=TDT-Small, TdtS; CC IsoId=P09838-2; Sequence=VSP_001309; CC Note=Major form; CC -!- SIMILARITY: Belongs to the DNA polymerase type-X family. CC -!- SIMILARITY: Contains 1 BRCT domain.
