What is SLC25A36 and why is it important for mitochondrial function?

SLC25A36 is a mitochondrial transporter that imports and exports pyrimidine nucleotides across the mitochondrial membrane. It selectively transports cytosine, guanosine, inosine, and uridine (deoxy)nucleoside mono-, di-, and triphosphates primarily through an antiport mechanism, though it can catalyze uniport at a much lower rate . This transporter plays a crucial role in providing precursors necessary for de novo synthesis of mitochondrial DNA and RNA while exporting products of their catabolism . SLC25A36 participates in three essential mitochondrial processes: genome maintenance, regulation of membrane potential, and mitochondrial respiration . Loss of SLC25A36 function in mouse embryonic stem cells has been associated with mitochondrial DNA loss and significant mitochondrial dysfunction, highlighting its importance in maintaining mitochondrial biogenesis .

What applications are SLC25A36 antibodies validated for?

Based on current research tools, SLC25A36 antibodies have been validated for multiple applications:

SLC25A36 antibodies have demonstrated reactivity with human samples , and some antibodies also cross-react with mouse and rat samples . When selecting an antibody, researchers should verify the specific applications and species reactivity needed for their experimental design .

What is the expected molecular weight for SLC25A36 detection?

When performing Western blot analysis, researchers should expect to observe SLC25A36 at approximately 32-34 kDa . This molecular weight information is critical for proper identification of the protein and for distinguishing it from other members of the solute carrier family 25 (SLC25). Any deviation from this expected molecular weight may indicate post-translational modifications, splicing variants, or potential antibody cross-reactivity that should be further investigated.

How can SLC25A36 antibodies be used to study mitochondrial nucleotide transport?

To study SLC25A36's role in nucleotide transport, researchers can employ several antibody-based approaches:
