Biological Activity

[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].

Research Areas >> Cancer

Signaling Pathways >> Metabolic Enzyme/Protease >> E1/E2/E3 Enzyme

[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].
