Protein

Mitochondrial basic amino acids transporter

Gene

SLC25A29

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Transports arginine, lysine, homoarginine, methylarginine and, to a much lesser extent, ornithine and histidine (PubMed:24652292). Can restore ornithine transport in cells lacking the primary mitochondrial ornithine transporter SLC25A15 (PubMed:19287344). Does not transport carnitine nor acylcarnitines (PubMed:24652292). Functions by both counter-exchange and uniport mechanisms (PubMed:24652292).2 Publications

Isoform 2 (identifier: Q8N8R3-2) [UniParc]FASTAAdd to basket

The sequence of this isoform differs from the canonical sequence as follows:
     13-145: VAGVLVGHPF...DCLAQIYGHE → TASGPERGEA...QPGHGVHVAA
     146-303: Missing.

Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.
