The inhibitory effect of miRNAs on their target molecules in the UPS pathway. Ubiquitin is transferred to the E2 enzyme after activation by the E1 enzyme, and is then transferred to the substrate by E3 enzyme. E4 enzyme is required for the formation of the polyubiquitin chain. After the recognition process, substrates are degraded by the 26S proteasome or their polyubiquitin monomers are removed by DUB.
