Screening methods as well as kits for identifying modulators of hydroxysteroid (17-beta) dehydrogenase (HSD17B) family member proteins, such as HSD17B13, are provided. The methods comprise screening molecules for their capacity to modulate the HSD17B family member protein, including inhibiting the HSD17B family member protein, as measured by substrate depletion, product concentration from the HSD17B family member protein substrate conversion or NADH concentration, levels of labeled substrate, luciferin light emission, or combinations thereof. Inhibitors of HSD17B family member proteins identified through the screening methods may be used to treat liver diseases, disorders, or conditions in which the HSD17B family member protein plays a role.
