Solute carrier family 25 member 51, also known as SLC25A51 and MCART1, is a protein which in humans is encoded by the SLC25A51 gene. This gene encodes a mitochondrial NAD+ transporter [1] and is a member of the mitochondrial carrier family of solute carrier proteins.
The SLC25A51 gene is located on the p arm of chromosome 9 in position 13.2 and spans 24,954 base pairs. [2] The gene produces a 33.7 kDa protein composed of 297 amino acids. [3] This gene has 6 exons and encodes a multi-pass integral membrane protein localized to the mitochondrial inner membrane. [2] [3]
The product of this gene (MCART1) is essential for the import of NAD+ into the mitochondria. [1] [4] [5]
Diseases associated with this gene include urea cycle disorders. [6]
