Protein Kinase Specificity
Matrix of observed frequency (%) of amino acids in aligned protein substrate phosphosites

Matrix Type:
Predicted from the application of the Kinexus Kinase Substrate Predictor Version 2.0 algorithm, which was trained with over 10,000 kinase-protein substrate pairs and 8,000 kinase-peptide substrate pairs.

Disease Linkage
Gene Expression in Cancers:
The COSMIC website notes an up-regulated expression score for TBCK in diverse human cancers of 284, which is 0.6-fold of the average score of 462 for the human protein kinases. The down-regulated expression score of 132 for this protein kinase in human cancers was 2.2-fold of the average score of 60 for the human protein kinases.
Mutagenesis Experiments:
Insertional mutagenesis studies in mice have not yet revealed a role for this protein kinase in mouse cancer oncogenesis.
Mutation Rate in All Cancers:
Percent mutation rates per 100 amino acids length in human cancers: 0.07 % in 24727 diverse cancer specimens. This rate is only -4 % lower and is very similar to the average rate of 0.075 % calculated for human protein kinases in general.
Mutation Rate in Specific Cancers:
Highest percent mutation rates per 100 amino acids length in human cancers: 0.36 % in 1270 large intestine cancers tested; 0.23 % in 864 skin cancers tested; 0.23 % in 589 stomach cancers tested; 0.22 % in 603 endometrium cancers tested; 0.14 % in 1634 lung cancers tested; 0.1 % in 548 urinary tract cancers tested; 0.1 % in 1512 liver cancers tested; 0.09 % in 127 biliary tract cancers tested; 0.08 % in 1459 pancreas cancers tested; 0.06 % in 382 soft tissue cancers tested; 0.05 % in 881 prostate cancers tested; 0.04 % in 833 ovary cancers tested; 0.04 % in 273 cervix cancers tested; 0.03 % in 710 oesophagus cancers tested; 0.03 % in 1316 breast cancers tested; 0.03 % in 1276 kidney cancers tested; 0.02 % in 942 upper aerodigestive tract cancers tested; 0.02 % in 558 thyroid cancers tested; 0.01 % in 2082 central nervous system cancers tested; 0.01 % in 2009 haematopoietic and lymphoid cancers tested.
Frequency of Mutated Sites:
Most frequent mutations with the number of reports indicated in brackets: R41C (4); Q504H (4).
Comments:
Eleven of the deletions mutants were at N457 located in the Rab-GAP domain.
