Hepatic proteins

Hepatic proteins refer to the collective group of proteins synthesized or localized in the liver, which are essential for maintaining systemic homeostasis, nutrient metabolism, and the detoxification of drugs and toxins (StatPearls, 2023). This broad category includes plasma proteins like albumin, various coagulation factors, and critical metabolic enzymes such as the Cytochrome P450 (CYP) family (NIH, 2024). Because the term encompasses thousands of distinct molecules with diverse functions, it is not considered a specific therapeutic target in drug discovery; rather, individual proteins within this group are targeted for specific indications (PubMed, 2022). For example, statins target HMG-CoA reductase, while anticoagulants like warfarin interact with vitamin K-dependent clotting factors. Monitoring the levels and activity of these proteins is a standard clinical practice to assess liver function and identify potential drug-induced liver injury (DILI). Furthermore, many drugs are metabolized by hepatic enzymes, making them central to understanding pharmacokinetics and potential drug-drug interactions.

The mechanism of action varies significantly depending on the specific hepatic protein involved, ranging from the inhibition of biosynthetic enzymes like HMG-CoA reductase to the induction or inhibition of metabolic enzymes such as Cytochrome P450 isoforms.
