2.A.29.8.9
Mitochondrial carrier protein CACL (CACT-like) (Solute carrier family 25 member 29).  Transports basic amino acids (Porcelli et al. 2014).  It transports arginine, lysine, homoarginine, methylarginine and, to a much lesser extent, ornithine and histidine. Carnitine and acylcarnitines were not transported by SLC25A29. This carrier catalyzes substantial uniport besides counter-exchange transport and exhibits a high transport affinity for arginine and lysine.  It is saturable and inhibited by mercurial compounds and other inhibitors of mitochondrial carriers to various degrees. The main physiological role of SLC25A29 is to import basic amino acids into mitochondria for mitochondrial protein synthesis and amino acid degradation (Porcelli et al. 2014).
