Proteintech α ube2f
(A) Schematic illustration of the regulatory relationship between UBE2M and <t>UBE2F</t> in regulating apoptosis. (B) Absolute growth rates of Sdhb +/+ and Sdhb -/- imCCs following knockdown with non-targeting control (shNT), shUBE2M, or shUBE2F. UBE2M knockdown selectively enhances growth in Sdhb -/- cells, while UBE2F knockdown strongly suppresses growth in both genotypes. P-values are calculated using Bonferroni correction for multiple t-tests and the number of asterisks indicates degree of significance. (C) Relative growth rates from (B) normalized to shNT controls, highlighting the lineage-specific increase in proliferation upon UBE2M knockdown in Sdhb -/- cells. Error bars account for propagation of error. (D) Western blot analysis of ubiquitylated NOXA (high-molecular-weight smear, ∼40–250 kDa), CUL5, UBE2F, UBE2M, GAPDH (loading control), and SDHB in Sdhb +/+ and Sdhb -/- imCCs after knockdown with shNT, shUBE2M, or shUBE2F. Protein depletion was observed only 8-10 cell doublings after treatment. The pattern suggests altered CUL5-associated substrate ubiquitylation upon UBE2F loss and stabilization of UBE2F substrates upon UBE2M depletion in the Sdhb -/- background.
