Description_x000D_ Biochem/physiol Actions_x000D_ SSO is an inhibitor of the respiratory chain happening in mitochondria. SSO targets the lysine 164 residue of the fatty acid binding site, observed in CD36 (cluster of differentiation 36), a scavenger receptor._x000D_ Sulfo-N-succinimidyl oleate (SSO; Sulfosuccinimidyl oleate) inhibits fatty acid translocase (CD36/FAT)-mediated signaling as well as long-chain fatty acid (LCFA) and oxidized low density lipoproteins (oxLDL) uptake in an irreversible manner via covalent modification of CD36 Lys164 within its FA- and oxLDL-binding domain. SSO is employed both in cultures (5-500 μM) and in animals in vivo (40 mg/kg i.p.) for studying CD36-mediated cellular and physiological functions.
