ETA is phosphorylated to PETA by CHK/ETNK

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.

在细胞质中，乙醇胺（ETA）由胆碱激酶（CHK）二聚体或乙醇胺激酶1/2（ETNK1/2）[Lykidis等，2001，Gallego-Ortega等，2009]磷酸化生成磷乙醇胺（PETA）。CHK二聚体由胆碱激酶α亚基（CHKA）或β亚基（CHKB）的同源二聚体，或由CHKA:CHKB的异源二聚体组成。
