Liu Y, Wang F, Zhang H, He H, Ma L, Deng X. Functional characterization of the Arabidopsis ubiquitin-specific protease gene family reveals specific role and redundancy of individual members in development. Plant J. 2008;55:844-56 pubmed publisher
..Although there are clearly functional redundancies among related sub-family members, those redundancies cannot be inferred simply based on the amino acid identity of the family members. ..

. Ubiquitin-specific protease16 modulates salt tolerance in Arabidopsis by regulating Na(+)/H(+) antiport activity and serine hydroxymethyltransferase stability. Plant Cell. 2012;24:5106-22 pubmed publisher
..Taken together, our results suggest that UBP16 is involved in salt tolerance in Arabidopsis by modulating sodium transport activity and repressing cell death at least partially through modulating SMH1stability and activity. ..

..Our results indicate that cold stress responses in Arabidopsis are attenuated by a ubiquitination/proteasome pathway in which HOS1 mediates the degradation of the ICE1 protein. ..

. The Arabidopsis elch mutant reveals functions of an ESCRT component in cytokinesis. Development. 2006;133:4679-89 pubmed
..Double mutants with tubulin folding cofactor a mutants show a synergistic phenotype, suggesting that ELC regulates cytokinesis through the microtubule cytoskeleton. ..

. The SUVR4 histone lysine methyltransferase binds ubiquitin and converts H3K9me1 to H3K9me3 on transposon chromatin in Arabidopsis. PLoS Genet. 2011;7:e1001325 pubmed publisher
..Our results imply that SUVR4 is involved in the epigenetic defense mechanism by trimethylating H3K9 to suppress potentially harmful transposon activity. ..

..Whereas transgenic plants expressing HisUb showed insignificant enrichment of ubiquitinated proteins, transgenic Arabidopsis lines expressing HisUbK48R gave a much better yield. ..

. The arabidopsis histone methyltransferase SUVR4 binds ubiquitin via a domain with a four-helix bundle structure. Biochemistry. 2014;53:2091-100 pubmed publisher
..The question of whether SUVR proteins act as both readers of monoubiquitinated H2B and writers of histone PTMs is discussed. ..
