Protein Kinase Classification: Atypical ABC1※ ABC1 family introduction ABC1 kinases are family of aarF domain-containing protein kinases which belong to atypical kinase group. Five members have been identified in human genome, known as ADCK1-ADCK5. ABC1 kinases contain the conserved protein kinase motifs which is responsible for the ATP binding and phosphotransfer reaction. However, as the overall sequence is distinct with ePK domain and lack of several usual kinase motifs, they are classified into "Atypical" kinase group (1).
