Official Symbol: SUMO2
Official Full Name: small ubiquitin-like modifier 2
Primary source: TAIR:AT5G55160
Locus tag: AT5G55160
See related: Araport:AT5G55160
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: ATSUMO2; MCO15.11; MCO15_11; small ubiquitin-like modifier 2; SMALL UBIQUITIN-LIKE MODIFIER 2; SUM2; SUMO 2
Summary: Encodes a small ubiquitin-like modifier (SUMO) polypeptide that becomes covalently attached to various intracellular protein targets, much like ubiquitination, leading to post-translational modification of those targets. SUMO2 can form SUMO chains through lysine residue 10 during in vitro assays.

What's a GeneRIF?

The study provides an insight into the molecular mechanism for understanding how the CHD3-like chromatin remodeling protein MOM1 cooperates with the SUMO E3 ligase-like proteins to regulate transcriptional silencing. [SUMO2]
Title: Exploring potential roles for the interaction of MOM1 with SUMO and the SUMO E3 ligase-like protein PIAL2 in transcriptional silencing.
Functionally similar to human SUMO2 and SUMO3, Arabidopsis SUMO1 and 2 can form chains, even though they do not possess a consensus SUMOylation motif. The surprising finding that plants have dedicated enzymes for chain synthesis implies a specific role for SUMO chains in plants
Title: SUMO Chain Formation by Plant Enzymes.
we provide evidence for the existence of a preferential conjugation of AtSUMO1/2 compared with AtSUMO3/5, which is determined by a role of the E1-activating enzyme in SUMO paralogue discrimination.
Title: Distinctive properties of Arabidopsis SUMO paralogues support the in vivo predominant role of AtSUMO1/2 isoforms.
SUM3 promotes plant defense downstream of salicylic acid, while SUM1 and SUM2 together prevent salicylic acid accumulation in noninfected plants.
Title: Arabidopsis small ubiquitin-like modifier paralogs have distinct functions in development and defense.
SIZ1-mediated conjugation of SUMO1 and SUMO2 to other intracellular proteins is essential in Arabidopsis, possibly through stress-induced modification of a potentially diverse pool of nuclear proteins.
Title: Genetic analysis of SUMOylation in Arabidopsis: conjugation of SUMO1 and SUMO2 to nuclear proteins is essential.
