Anti-TENT4A antibodies are used in the immunodetection of the protein terminal nucleotidyltransferase 4A. In humans, the canonical protein has a reported length of 792 amino acid residues and a mass of 84.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the DNA polymerase type-B-like protein family, TENT4A is reported to be a terminal nucleotidyltransferase that catalyzes preferentially the transfert of ATP and GTP on RNA 3' poly(A) tail creating a heterogeneous 3' poly(A) tail leading to mRNAs stabilization by protecting mRNAs from active deadenylation. Synonyms for this target antigen include LAK1, PAPD7, POLK, POLS, TRF4, TRF4-1, TRF41, and LAK-1. TENT4A gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. These TENT4A antibodies are widely used in Western Blot experiments, among other applications.
