The home page has three basic ways of identifying individual kinases, and all are clickable: The top level------------------------------------------------------ 1) Tony Hunter et al's. dendrogram (or PFAM domains, for the plant kinases which have no human counterpart). 2) Structural motifs. 3) Entropy and covariation analysis, plotted above a clickable 'representatife sequence' alignment. ------------------------------------------------------------------ FROM the dendrogram (1) Clicking on the dendrogram / pfam diagram takes you to one of ten family pages. Fixed-width (399 amino acid) pdf alignments of (on average 600) kinases for each family, sorted in order of a maximum - likelihood phylogenetic tree, as well as pdf files of the trees, with and without additional pfam domains listed are available at the top. A certain amount of information (PDB links, Pfam links, PhosphoBase links) are included. I have a separate set of literature links, which could be made into Pub-Med links, but I have no plans to provide complete coverage. Sequence entropy withing the family and covariation analysis is provided. PDB files are provided with numbers according to the global sequence alignment, so that this information can be easily visualized (cut and paste, eg. low entropy residues, into, eg. VMD). Representative sequences for each family are shown under the sequence analysis. From the family level, it is possible to decend into, on average, 6 subfamilies or directly to an individual kinase page, by clicking on Tony Hunter's dendrogram. The subfamily page has a png of the relevent subfamily tree, as well as representative sequences from the subfamily plotted under the statistical analysis for each subfamily. Each of the 333 group kinase pages has jpeg and pdb files of homology models of the 491 human varients of the catalytic subunit, as well as Clustal alignments of the full protein sequence (all domains) for the group, plus one or more sequences from the PDB sequence file. Web-links back to GenBank / RefSeq. are provided for all non-rice and non-human kinases. (rice sequences were provided to me as a personal communcation and Human kinases were taken from Tony Hunter's Science paper -- all others were RefSeq. release 3, and could be linked). ------------------------------------------------------------------- FROM the structural motifs: each structral motif takes you to a multiple sequence alignment of, eg., the E helix from each of the 500 human kinases. This alignment (as are all of the representative sequence alignments) is clickable, taking you to a replication of Tony Hunter' dendrogram, with the residue at this position plotted as a color- and shape- coded symbol. -------------------------------------------------------------------- FROM the representative sequences: The main kinase page, each of the 10 families, and each of the 61 subfamilies has a clickable representative sequence alignment, with sequence entropy and covariation analysis over the respective subset plotted. Clicking on a residue takes you to a dendrogram showing this residue's distribution across the human kinases. IMPORTANTLY, this dendrogram is clickable, taking you to the bottom of the hierarchical classification, where you can work your way back up through the group, subfamily, and family hierarichy.
