2.A.1.13.5
Low affinity monocarboxylate transporter-2 (MCT2). Transports γ-hydroxybutyrate (Wang and Morris, 2007). MCT2 requires the ancillary protein, embigin (Q6PCB8; 8.A.23.1.2) for plasma membrane localization (Ovens et al., 2010). It is present in neurons but not astrocytes where the low affinity MCT1 and MCT4 predominate (Hertz and Dienel 2013). Partially localizes to the peroxysomal membrane (Visser et al. 2007). MCT1 is a negative regulator and MCT2 a positive regulator of osteoclast differentiation, while MCT2 is required for bone resorption by osteoclasts (Imai et al. 2019). Atorvastatin exerts more selective inhibitory effects on hMCT2 than on hMCT1 and hMCT4 (Yamaguchi et al. 2023).
