WebSuppressor of variegation 3–9 [Su (var)3–9] was first described in Drosophila as a complementation group in a genetic screen for dominant mutations that suppress heterochromatin-mediated silencing. The 3–9 refers to the ninth complementation group on the third chromosome of D. melanogaster. WebApr 14, 2024 · Histone methyltransferase SUV39H2 (suppressor of variegation 3-9 homolog 2) accumulates on the sex body region in pachytene spermatocytes to modulate heterochromatin (O'Carroll et al., 2000). Heterochromatin protein 1 (HP1), which binds to H3K9me3, is shown to be related to chromatin condensation and transcription regulation.

WebMar 18, 2013 · Suppressor of variegation 3–9 homolog 1 (SUV39H1) is an evolutionarily conserved homolog of Drosophila Su(var)3–9, which functions as a histone methyltransferase that mainly catalyzes the trimethylation of histone 3 lysine 9 (H3K9) in vivo (8, 9).SUV39H1 is critical for the establishment and maintenance of heterochromatin … Webteins, that is svr4-1 is probably a bypass suppressor (data not shown). Because the ‘suppression of variegation’ phenotype co-segregates with the virescent phenotype, we were able to use this trait as a marker to clone the suppressor gene by map-based methods.
