Kinase classification map. Based on the similarity of kinase domain sequences, 518 human protein kinases were divided into nine groups: tyrosine kinase group (TK group), tyrosine kinase-like group (TKL group), homologs of yeast Sterile 7, Sterile 11, Sterile 20 kinases group (STE group), containing PKA, PKG, PKC families group (AGC group), calcium/calmodulin-dependent protein kinase group (CAMK group), containing CDK, MAPK, GSK3, CLK families group (CMGC group), casein kinase 1 group (CK1 group), other group, atypical protein kinase group. Proteins of pathological significance for neurodegenerative diseases were highlighted in the figure using different colors as indicated in the figure.
