General description

UNC0638 enhances the E-cadherin expression in gemcitabine-resistant cell line (PANC-1-R).

Application

UNC0638 hydrate has been used:
  • in fractionation and isolation of human blood cells and cell nuclei
  • in the analysis of human immunodeficiency virus (HIV) reactivation in latently infected cell line
  • to determine the effect of G9a and its enzymatic activity on cisplatin resistance

UNC0638 has been used to block G9a (a lysine methyltransferase) function in C2C12 cells. UNC0638 has also been reported to decrease H3K9 dimethylation (H3K9me2) levels and inhibit cell death in hair cells.

Packaging

5, 25 mg in glass bottle

Biochem/physiol Actions

UNC0638 hydrate is a histone methyltransferase (HMT) inhibitor. UNC0638 shows selectivity for G9a (EHMT2) and GLP (EHMT1) methyltransferases, which catalyze the methylation of lysine 9 of histone 3 (H3K9) as well as other non-histone substrates. For full characterization details, please visit the UNC0638 probe summary on the Structural Genomics Consortium (SGC) website.
