SLC22A2
SLC22A2 is a gene that encodes a protein known as the Organic Cation Transporter 2 (OCT2). This protein is a member of the solute carrier family of proteins, which are responsible for transporting various substances across the cell membrane.
Function[edit | edit source]
The SLC22A2 gene is primarily expressed in the kidney, where it plays a crucial role in the elimination of various endogenous and exogenous substances. The protein encoded by this gene is involved in the transport of organic cations, including various drugs and toxins. It is an important factor in drug disposition and response.
Clinical significance[edit | edit source]
Mutations in the SLC22A2 gene can lead to altered drug response and toxicity. For example, certain variants of this gene have been associated with increased risk of cisplatin nephrotoxicity. Furthermore, the SLC22A2 gene is a potential target for drug interactions, as many drugs are substrates for the OCT2 transporter.
Pharmacogenomics[edit | edit source]
The SLC22A2 gene is of interest in the field of pharmacogenomics, as variations in this gene can influence an individual's response to certain medications. For example, individuals with certain SLC22A2 variants may require different dosages of drugs that are substrates for the OCT2 transporter, such as metformin.
