A pharmaceutical composition for preventing and treating metabolic diseases, which includes an MKRN1 expression or activity inhibitor as an active ingredient, is provided. Because the MKRN1 of the present invention functions as an E3 ligase, which ubiquitinates AMPKα, to degrade an AMPK protein, expression and activity levels of AMPK can be restored by suppressing the MKRN1 expression. Also, the MKRN1 expression or activity inhibitor of the present invention can be effectively used as an active ingredient of the composition for preventing and treating metabolic diseases because an improving effect on obesity, diabetes, and fatty liver can be exhibited by MKRN1 expression knockout in a mouse model in which the MKRN1 expression is knocked out and the obesity, diabetes and fatty liver are induced by high-fat diets. |
