tRNA nucleotidyltransferase (tRNA adenylyltransferase)

05/02/2023 - "Sideroblastic anaemia with B-cell immunodeficiency, periodic fever and developmental delay is a recently described, rare syndrome characterised by numerous manifestations underpinned by mutations in transfer RNA nucleotidyltransferase. "
01/01/2016 - "SIFD (Sideroblastic anemia with B-cell immunodeficiency, periodic fevers, and developmental delay) is a novel form of congenital sideroblastic anemia associated with B-cell immunodeficiency, periodic fevers, and developmental delay caused by mutations in the CCA-adding enzyme TRNT1, but the precise molecular pathophysiology is not known. "
01/01/2023 - "We recently discovered that partial loss-of-function mutations in tRNA Nucleotidyl Transferase 1 (TRNT1), the nuclear gene encoding the CCA-adding enzyme essential for modifying both nuclear and mitochondrial tRNAs, causes a multisystemic and clinically heterogenous disease termed SIFD (sideroblastic anemia with B-cell immunodeficiency, periodic fevers, and developmental delay; SIFD). "
01/01/2023 - "Sideroblastic anemia with B-cell immunodeficiency, periodic fevers, and developmental delay (SIFD) is a serious autosomal recessive syndrome caused by biallelic mutations in cytosine-cytosine-adenosine tRNA nucleotidyltransferase 1 (TRNT1). "
03/01/2020 - "Mutations in the gene encoding transfer RNA (tRNA) nucleotidyltransferase, CCA-adding 1 (TRNT1), an enzyme essential for the synthesis of the 3'-terminal CCA sequence in tRNA molecules, are associated with a rare syndrome of congenital sideroblastic anemia, B cell immunodeficiency, periodic fevers, and developmental delay (SIFD).

"
04/01/2018 - "Mutations in the human TRNT1 gene encoding tRNA nucleotidyltransferase (tRNA-NT), an essential enzyme responsible for addition of the CCA (cytidine-cytidine-adenosine) sequence to the 3'-termini of tRNAs, have been linked to disease phenotypes including congenital sideroblastic anemia with B-cell immunodeficiency, periodic fevers and developmental delay (SIFD) or retinitis pigmentosa with erythrocyte microcytosis. "

10/01/1987 - "When the cytosol of Ehrlich ascites tumor cells was fractionated by chromatofocusing in the pH range of 9 to 6, two active peaks (I and II) of tRNA nucleotidyltransferase were obtained. "
03/01/1979 - "The tRNA nucleotidyltransferase activity (3H-CMP incorporation into 3'-terminus of tRNApC) in cytoplasmic fractions of various types of cells such as Ehrlich ascites tumor cells, mouse liver and spleen cells, rat spleen, lymph node, and macrophages cells was found to be dependent on the concentrations of nucleoside 5'-triphosphates (ATP, GTP, UTP, dATP, dGTP, dCTP, and/or dTTP). "

07/01/2000 - "An altered KlCCA1 gene encoding a tRNA nucleotidyltransferase that lacked its first 35 amino acids was able to complement the nuclear/cytosolic but not the mitochondrial defect in the S. "
