General annotation (Comments)

Function

E3 SUMO protein ligase involved in regulation processes. Mediates SUMO/ attachment to PHR1, a MYB transcriptional activator controlling the phosphate deficiency responses. Functions as an upstream negative regulator of salicylic acid (SA) accumulation and subsequent SA-mediated systemic acquired resistance (SAR) signaling. Probably not involved in jasmonic acid (JA)-mediated defense response. Participates in abiotic stress-induced sumoylation. Controls heat shock-induced SUMO1 and SUMO2 conjugation and facilitates basal thermotolerance. Involved in freezing tolerance by mediating sumoylation of ICE1, a transcription activator of the cold signaling regulator CBF3/DREB1A. Acts as positive regulator of drought stress tolerance. Acts as floral repressor that promotes FLC expression by repressing FLD activity through sumoylation. Acts as negative regulator of abscisic acid (ABA) signaling through ABI5 sumoylation. Mediates sumoylation of SCE1, GTE3 and GTE5. Ref.7 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13 Ref.14 Ref.15 Ref.16

Pathway

Protein modification; protein sumoylation.

Subunit structure

Interacts (via PHD domain) with SCE1, GTE3 and GTE5. Ref.14

Subcellular location

Nucleus speckle Ref.7.

Tissue specificity

Ubiquitous. Ref.11

Domain

The PHD-type zinc finger mediates interaction with SCE1, GTE3 and GTE5 and is required for E3 activity. Ref.14

Post-translational modification

Autosumoylated at Lys-100 and Lys-488. Ref.14

Disruption phenotype

Dwarf phenotype. Heat-sensitive phenotype. Early flowering under short day. Elevated level of salicylic acid (SA), increased expression of pathogenesis-related (PR) genes and increased resistance to the bacterial pathogen P.syringae. ABA hypersensitivity during seed germination primary root growth. Ref.9 Ref.11 Ref.12 Ref.13 Ref.15 Ref.16

Sequence similarities

Belongs to the PIAS family.

Contains 1 PHD-type zinc finger.

Contains 1 SAP domain.

Contains 1 SP-RING-type zinc finger.
