Tpz1TPP1 SUMOylation reveals evolutionary conservation of SUMO-dependent Stn1 telomere association [PDF]

, 2014
Elongation of the telomeric overhang by telomerase is counteracted by synthesis of the complementary strand by the CST complex, CTC1(Cdc13)/Stn1/Ten1. Interaction of budding yeast Stn1 with overhang-binding Cdc13 is increased by Cdc13 SUMOylation. Human

SUMOylation of claudin‐2 [PDF]

Annals of the New York Academy of Sciences, 2012
The C‐terminal cytoplasmic tails of claudins are likely sites for interaction with proteins that regulate their function. We performed a yeast two‐hybrid screen with the tail of human claudin‐2 against a human kidney cDNA library and identified interactions with the PDZ3 domain of ZO‐2 as well as ubiquitin‐conjugating enzyme E2I (SUMO ligase‐1) and E3 ...

Forkhead box protein A2 (FOXA2) protein stability and activity are regulated by sumoylation. [PDF]

PLoS ONE, 2012
The forkhead box protein A2 (FOXA2) is an important regulator of glucose and lipid metabolism and organismal energy balance. Little is known about how FOXA2 protein expression and activity are regulated by post-translational modifications.

Homologous Recombination: To Fork and Beyond [PDF]

, 2018
Accurate completion of genome duplication is threatened by multiple factors that hamper the advance and stability of the replication forks. Cells need to tolerate many of these blocking lesions to timely complete DNA replication, postponing their repair ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

IKK phosphorylates Huntingtin and targets it for degradation by the proteasome and lysosome [PDF]

, 2009
Expansion of the polyglutamine repeat within the protein Huntingtin (Htt) causes Huntington's disease, a neurodegenerative disease associated with aging and the accumulation of mutant Htt in diseased neurons.

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

FEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

SUMOylation is essential for Sirt2 tumor-suppressor function in neuroblastoma

Neoplasia: An International Journal for Oncology Research, 2021
SUMOylation is an important post-translational modification that participates in a variety of cellular physiological and pathological processes in eukaryotic cells. Sirt2, a NAD+-dependent deacetylase, usually exerts a tumor-suppressor function. However,

Divergent Regulatory Effects of Jasmonic Acid on Tomato Lycopene Biosynthesis Under Light and Dark Conditions

Advanced Science, EarlyView.
This study reveals the mechanism by which jasmonic acid (JA) regulates lycopene synthesis under light and dark conditions. In light, JA activates SlMYC2, which suppresses SlPIF1a and promotes SlPSY1 expression. In darkness, JA induces the acetyltransferase SlNATA1, which acetylates the dark‐accumulated SlPIF1a, thereby repressing SlPSY1 expression ...
