SLC46A1 - Proton-coupled folate transporter
Order number: 71431
Description
We are excited to introduce our off-the-shelf, full-length, active, and native Proton-coubled folate transporter, as known as SLC46A1. SLC46A1 is a proton-coupled folate transporter that mediates the uptake of folate across the intestinal epithelium and its transport into tissues. Functions as a symporter that transports folate together with protons, enabling efficient absorption under acidic conditions.
Our SLC46A1 protein has been solubilized and stabilized using Cube Biotech's NativeMP™ platform, ensuring it retains its native structure and full biological activity, making it ideal for a wide range of research applications.
Applications:
- Screening/Validation
- Biologics Development
- Structure Determination
- Small Molecule Drug Development
The protein delivered can be used for these specific applications. When ordering, please indicate which applications you intend to use the protein for in the contact form to ensure the best results.
