Description

SMER3, a Rapamycin enhancer, is a selective Skp1-Cullin-F-box (SCF)Met30 ubiquitin ligase inhibitor. SMER3 enhances Rapamycin's growth inhibitory effect by inhibition of SCFMet30[1].

In Vitro

In yeast cells, Met4 ubiquitination is blocked in cells exposed to SMER3 (0-60 μM). The met4Δ cells are less susceptible to growth inhibition by SMER3[1].
Addition of SMER3 to the ligase reactions inhibited ubiquitination of Met4 by SCFMet30 in a dose-dependent manner. SMER3 significantly inhibits the binding of Met30 to Skp1, and does not affect the Skp1 and Met30 protein levels[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
