WebMar 29, 2024 · G9a contributes to multiple steps of ovarian cancer metastasis. H3K9 methyltransferase G9a plays role in the apoptosis and autophagy in oral squamous cell carcinoma. Genetic or pharmacological inhibition of G9a reduced cell proliferation without inducing necrosis or apoptosis. Results show that G9a acts positively to promote tumor … WebG9a (Figure S1), and it is reasonable to assume that the peptide binding mode observed in GLP holds for G9a. On the other hand, mutation of R-1 to alanine only mildly affects peptide binding to Dim-5, a H3K9 methyltransferase in N. crassa [31], indicating that the selectivity mechanism observed for human GLP and G9a is not universal.
