ABCD4 - Lysosomal cobalamin transporter ABCD4
Order number: 71531
Description
We are excited to introduce our off-the-shelf, full-length, active, and native Lysosomal cobalamin transporter ABCD4. ABCD4 is an ATP-binding cassette (ABC) transporter located in lysosomal membranes that mediates the ATP-dependent export of vitamin B₁₂ (cobalamin) into the cytosol. Loss-of-function mutations in ABCD4 are linked to cobalamin deficiency disorders.
Our ABCD4 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.
