In the cytosol, ethanolamine (ETA) is phosphorylated to phosphoethanolamine (PETA) by choline kinase (CHK) dimer or by ethanolamine kinase 1/2 (ETNK1/2) (Lykidis et al. 2001, Gallego-Ortega et al. 2009). CHK dimer consists of either choline kinase alpha subunit (CHKA) or beta subunit (CHKB) homodimer, or of CHKA:CHKB heterodimer.
