Is predicted to encode a protein with the following domains: Protein kinase-like domain superfamily and Choline/ethanolamine kinase. Is an ortholog of C. elegans ckb-1; ckb-2; and ckb-3.
Is predicted to encode a protein with the following domains: Protein kinase-like domain superfamily and Choline/ethanolamine kinase. Is an ortholog of C. elegans ckb-4. In C. elegans, ckb-4 is involved in CDP-choline pathway.
