Distinct SUMO ligases cooperate with Esc2 and Slx5 to suppress duplication-mediated genome rearrangements. [PDF]
PLoS Genetics, 2013 Suppression of duplication-mediated gross chromosomal rearrangements (GCRs) is essential to maintain genome integrity in eukaryotes. Here we report that SUMO ligase Mms21 has a strong role in suppressing GCRs in Saccharomyces cerevisiae, while Siz1 and ...

Proteasome Lid Bridges Mitochondrial Stress with Cdc53/Cullin1 NEDDylation Status [PDF]
, 2019 Cycles of Cdc53/Cullin1 rubylation (a.k.a NEDDylation) protect ubiquitin-E3 SCF (Skp1-Cullin1-F-box protein) complexes from self-destruction and play an important role in mediating the ubiquitination of key protein substrates involved in cell cycle ...

A role for non-covalent SUMO interaction motifs in Pc2/CBX4 E3 activity. [PDF]
PLoS ONE, 2010 Modification of proteins by the small ubiquitin like modifier (SUMO) is an essential process in mammalian cells. SUMO is covalently attached to lysines in target proteins via an enzymatic cascade which consists of E1 and E2, SUMO activating and ...

Regulation of alphaherpesvirus infections by the ICP0 family of proteins [PDF]
, 2013 Immediate-early protein ICP0 of herpes simplex virus type 1 (HSV-1) is important for the regulation of lytic and latent viral infection. Like the related proteins expressed by other alphaherpesviruses, ICP0 has a zinc-stabilized RING finger domain that ...

Meiosis and small ubiquitin‐related modifier (SUMO)‐conjugating enzyme, Ubc9 [PDF]
The FEBS Journal, 2007 In this review, we describe the role of a small ubiquitin‐like protein modifier (SUMO)‐conjugating protein, Ubc9, in synaptonemal complex formation during meiosis in a basidiomycete, Coprinus cinereus. Because its meiotic cell cycle is long and naturally synchronous, it is suitable for molecular biological, biochemical and genetic studies of meiotic ...

SUMOylation of NaV1.2 channels mediates the early response to acute hypoxia in central neurons. [PDF]
, 2016 The mechanism for the earliest response of central neurons to hypoxia-an increase in voltage-gated sodium current (INa)-has been unknown. Here, we show that hypoxia activates the Small Ubiquitin-like Modifier (SUMO) pathway in rat cerebellar granule ...
