Target data

Function

Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Probably recognizes and binds to phosphorylated target proteins during skeletal muscle atrophy. Recognizes TERF1.

    AG/UnAG attenuates ubiquitin E3 legases expression in co-cultured myotubes(A) Western blot of atrogin-1, MuRF1 and GAPDH in C2C12 myotubes. (B) Quantification of atrogin-1 was normalized to GAPDH. Significant differences were detected between CO and any NC groups (#P < 0.001), between CO and CO+AG/UnAG groups (*P = 0.001, P < 0.001; respectively), by one-way ANOVA followed by Tukey test. (C) Quantification of MuRF1 was normalized to GAPDH. Significant differences were detected between CO and any NC groups (#P = 0.002), between CO and CO+AG/UnAG groups (*P = 0.015, P = 0.037; respectively), by one-way ANOVA followed by Tukey test. (D) The levels of atrogin-1 mRNA in C2C12 myotubes. mRNA levels were normalized to GAPDH. Significant differences were detected between NC and CO groups (#P = 0.024), between CO and CO+AG/UnAG groups (*P = 0.034, P = 0.033; respectively), by one-way ANOVA followed by Dunnett's T3 test. (E) The levels of MuRF1 mRNA in C2C12 myotubes. mRNA levels were normalized to GAPDH. Significant differences were detected between NC and CO groups (#P = 0.006, P = 0.006; P = 0.007 respectively), between CO and CO+AG groups (*P = 0.016, P = 0.012), by one-way ANOVA followed by Tukey test.
