DNA damage induces Yap5-dependent transcription of ECO1/CTF7 in Saccharomyces cerevisiae.

open access: yesPLoS ONE, 2020
Yeast Eco1 (ESCO2 in humans) acetyltransferase converts chromatin-bound cohesins to a DNA tethering state, thereby establishing sister chromatid cohesion.

Conserved interactions of the splicing factor Ntr1/Spp382 with proteins involved in DNA double-strand break repair and telomere metabolism [PDF]

open access: yes, 2007
The ligation of DNA double-strand breaks in the process of non-homologous end-joining (NHEJ) is accomplished by a heterodimeric enzyme complex consisting of DNA ligase IV and an associated non-catalytic factor. This DNA ligase also accounts for the fatal

Ubiquitylation in immune disorders and cancer: from molecular mechanisms to therapeutic implications [PDF]

open access: yes, 2012
Conjugation of ubiquitin to proteins (ubiquitylation) has emerged to be one of the most crucial post-translational modifications controlling virtually all cellular processes.

Mammalian DNA ligases. Biosynthesis and intracellular localization of DNA ligase I.

open access: yesJournal of Biological Chemistry, 1990
Mammalian DNA ligase I is presumed to act in DNA replication. Rabbit antibodies against the homogeneous enzyme from calf thymus inhibited DNA ligase I activity and consistently recognized a single polypeptide of 125 kDa when cells from an established bovine kidney cell line (MDBK) were lysed rapidly by a variety of procedures and subjected to ...

Temperature dependence of circular DNA topological states

open access: yes, 2009
Circular double stranded DNA has different topological states which are defined by their linking numbers. Equilibrium distribution of linking numbers can be obtained by closing a linear DNA into a circle by ligase.

Molecular genetics of auxin signaling [PDF]

open access: yes, 2002
The plant hormone auxin is a simple molecule similar to tryptophan, yet it elicits a diverse array of responses and is involved in the regulation of growth and development throughout the plant life cycle.

Mammalian DNA ligases. Catalytic domain and size of DNA ligase I.

open access: yesJournal of Biological Chemistry, 1990
DNA ligase I is the major DNA ligase activity in proliferating mammalian cells. The protein has been purified to apparent homogeneity from calf thymus. It has a monomeric structure and a blocked N-terminal residue. DNA ligase I is a 125-kDa polypeptide as estimated by sodium dodecyl sulfate-gel electrophoresis and by gel chromatography under denaturing

Case Report: Hypomorphic Ligase 4 deficiency – a paradigm of immunodysregulation

open access: yesFrontiers in Immunology
DNA Ligase 4 is critical to nonhomologous end joining, necessary for V(D)J recombination in T and B cell development. Ligase 4 deficiency is a rare autosomal recessive disorder caused by hypomorphic mutations in the DNA Ligase 4 gene, that can lead to a ...

Evolution of DNA ligases of Nucleo-Cytoplasmic Large DNA viruses of eukaryotes: a case of hidden complexity

open access: yesBiology Direct, 2009
Background Eukaryotic Nucleo-Cytoplasmic Large DNA Viruses (NCLDV) encode most if not all of the enzymes involved in their DNA replication. It has been inferred that genes for these enzymes were already present in the last common ancestor of the NCLDV ...

Rsp5 promotes Gene Activation mediated by 9aaTAD Transcription Factors Oaf1 and Gal4 [PDF]

open access: yes, 2009
Nine-amino-acid transactivation domain, 9aaTAD, defines a large superfamily of yeast and mammals transcription factors. The transactivation of the 9aaTAD has been addressed to multiple general co-activators TAF9, MED15, CBP and p300.
