Protein tyrosine kinase 2beta (PTK2B) is a member of the focal adhesion kinase family and is activated by angiotensin II through Ca2+-dependent pathways. An evidence exists that PTK2B is involved in cell growth, vascular contraction, inflammatory responses, and salt and water retention through activation of the angiotensin II type 1 receptor. To examine the contribution of PTK2B, we sequenced the PTK2B gene using 48 patients with hypertension, identified 62 genetic polymorphisms, and genotyped six representative single nucleotide polymorphisms in population-based case-control samples from 3655 Japanese individuals (1520 patients with hypertension and 2135 controls). Multivariate logistic regression analysis after adjustments for age, body mass index, present illness (hyperlipidemia and diabetes mellitus), and lifestyle (smoking and drinking) showed -22A>G to have an association with hypertension in men (AA vs. AG+GG: odds ratio=1.27; 95% confidence interval: 1.02-1.57; P=0.030). Another polymorphism, 53484A>C (K838T), in linkage disequilibrium with -22A>G showed a marginal association with hypertension in men (AA vs. AC+CC: odds ratio=1.25; 95% confidence interval: 0.99-1.57; P=0.059). Diastolic blood pressure was 1.6 mmHg higher in men with the AC+CC genotype of 53484A>C than those with the AA genotype (P=0.003), after adjustments for the same factors. These polymorphisms are in linkage disequilibrium with others in a range of 113 kb in PTK2B. The intracellular distribution of the recombinant PTK2B protein and that of the mutant protein with T838 were indistinguishable even after angiotensin II stimulation, both proteins localizing at a focal point in the peripheral area in the cells. Thus, a haplotype in PTK2B may play a role in essential hypertension in Japanese.
