The skeletal muscle, Na+-dependent, choline transporter-like protein, CTL-1 (SLC44A1; 653 aas) (Yuan et al., 2004) (Present in the plasma membrane, mitochondria and endosomes; catalyzes choline uptake into mitochondria (Michel and Bakovic, 2009).

The inner ear choline transporter-like transporter glycoprotein CLT-2 (CTL2; SLC44A2; 706 aas), target of autoimmune hearing loss (Nair et al., 2004; Kleopa, 2011).  CTL2 co-precipitates with multiple isoforms of cochlin (TC# 8.A.54.1.3) which is mutated in individuals with DFNA9 hearing loss (Kommareddi et al. 2007).

Choline transporter, choline transporter-like protein 1 (CDw92) (Solute carrier family 44 member 1) (CD antigen CD92).  The transcriptional regulation and splice variation of the encoding gene have been studied (Yuan et al. 2006). It is found in many tissues including red blood cells (Bryk and Wiƛniewski 2017). May be involved in neurodevelopmental disorders (Reuter et al. 2017). CTL1 and CTL2 proteins are present in the plasma membrane and mitochondria, respectively. They have intermediate affinities for choline (Iwao et al. 2016).
