6. Results show that VEGFA induces Pyk2 activation in mediating human retinal microvascular endothelial cell migration, sprouting and tube formation, and that Pyk2-mediated STAT3 activation is required for hypoxia-induced retinal neovascularization.

7. Interestingly, rs2279590 locus has a widespread enhancer effect on two nearby genes, protein tyrosine kinase 2 beta (PTK2B) and epoxide hydrolase-2 (EPHX2); both of which have been previously associated with AD as risk factors.

8. thrombin binding to PAR-1 receptor activated Gi-protein/c-Src/Pyk2/EGFR/PI3K/Akt/p42/p44 MAPK cascade, which in turn elicited AP-1 activation and ultimately evoked MMP-9 expression and cell migration in SK-N-SH cells.

10. In summary, our data suggested that PYK2 via S6K1 activation modulated AR function and growth properties in prostate cancer cells. Thus, PYK2 and S6K1 may potentially serve as therapeutic targets for PCa treatment.

11. Our findings suggest that Pyk2 plays an important role in the coordination of stabilization of beta-catenin in the crosstalk between Wnt/beta-catenin and Wnt/Ca(2+) signaling pathways upon Wnt3a stimulation in differentiating hNPCs.

12. STIM1-induced Ca(2+) signaling activates Pyk2 to inhibit the interaction of VE-PTP and VE-cadherin and hence increase endothelial permeability.

13. Ascites and CCL18 stimulate the phosphorylation and expression of Pyk2, which positively regulates ascites-induced ovarian cancer cell migration.

14. We demonstrated trophoblast cytoprotection by intervention with supraphysiological concentrations of relaxin, a process in part mediated through the PI3-kinase-Akt/PKB cell survival pathway. These results provide further rationale for clinical investigation of relaxin as a potential therapeutic in preeclampsia.

15. PTK2B polymorphism (rs28834970) could modify the risk of late-onset Alzheimer's disease (LOAD), and PTK2B polymorphism (rs28834970) and APOE may interact to increase LOAD risk in a Han Chinese population.

16. Studies suggest that PYK2 is a common downstream effector of ErbB and IL8 receptors, and that PYK2 integrates their signaling pathways through a positive feedback loop to potentiate breast cancer invasion.

17. Pyk2 is a key downstream signaling molecules of CCR7 in SCCHN, which promotes SCCHN tumorigenesis and progression.

18. Phosphoproteomic analysis identifies FAK2 as a potential therapeutic target for tamoxifen resistance in breast cancer.

19. Pyk2-focal adhesion targeting domain interacts with and binds to leupaxin.

20. Src has a role in priming Pyk2 (but not FAK) phosphorylation and subsequent activation downstream of integrins

Mouse (Murine) PTK2B Protein tyrosine Kinase 2 beta (PTK2B) interaction partners

1. Pyk2 is involved in the process of colonic smooth muscle contraction through the RhoA/ROCK pathway.

2. This study reveals a novel role for Pyk2 as a direct tyrosine kinase of tau that is active downstream of Fyn.

3. The study results reveal a possible role for Pyk2 in the response to stress and in synaptic markers expression and spine density regulation in the amygdala. It suggests that Pyk2 contributes to stress-induced responses through micro-structural changes and that its deficit may contribute to the resilience to chronic stress.

4. the role of estrogen signaling on the mechanism of action of Pyk2 in osteoblasts, was examined.

5. Data indicate a molecular protocadherin alpha (Pcdhalpha)/Wiskott-Aldrich syndrome potein Family (WAVE)/proline-rich tyrosine kinase 2 (Pyk2)/Rac1 axis from protocadherin cell-surface receptors to actin cytoskeletal dynamics in cortical neuron migration and dendrite morphogenesis in mouse brain.

6. In the absence of Pky2 there is a slight decrease in plaque formation in cortex and hippocampus and an increase in plaque formation following Pky2 over-expression.

7. Pyk2 has a role in spine structure and synaptic function; its deficit contributes to Huntington's disease cognitive impairments

8. the non-receptor protein tyrosine kinase 2 beta (PTK2B) plays a critical role in murine beige adipocyte differentiation.

9. Data provide evidence that activated PYK2 may function as a component of the microtubule organizing center to regulate spindle assembly during the meiotic process of mouse oocytes.

10. MMP-9 activation by hypoxia requires LRP1 and Pyk2 phosphorylation in fibroblasts.

11. results suggest that although Pyk2 and FAK are involved in inflammasome activation, only Pyk2 directly phosphorylates ASC and brings ASC into an oligomerization-competent state by allowing Tyr146 phosphorylation to participate ASC speck formation and subsequent NLRP3 inflammation.

12. Osteoprotegerin may induce podosome reassembly and peripheral adhesive structure detachment by modulating phosphorylation of Pyk2 and Src and their intracellular distribution in osteoclasts.

13. These results suggest that mechanical stimuli activate P2X7 might induce ECMPs expression through PYK2 except in the case of OPN expression. Altogether, mechanical stimuli-induced ECMPs production might be implicated by extracellular ATP secretion or integrin via PYK2 activation.

14. Lineage-tracing of monocyte populations suggests that Pyk2 promotes apoptosis in BM monocytes, thereby acting as an important homeostatic regulator of turnover in these short-lived, innate immune cells.

15. Pyk2 selectively contributes to the coordination of phagocytosis-promoting signals downstream of CR3, but is dispensable for FcgammaR-mediated phagocytosis

16. the findings suggest a model in which the oocyte is not a passive participant in fertilization, but instead responds to sperm contact by localized PYK2 signaling that promotes actin remodeling events required to physically incorporate the sperm head into the ooplasm.

17. results show that Pyk2 contributes to cytotoxic T lymphocyte(CTL) migration by regulating detachment of CTL at the trailing edge, which could explain why Pyk2 is important for chemotactic and migratory responses.

18. Defects in Pyk2 suppress Kawasaki Disease-like experimental vasculitis, presumably through CXCL9- and CXCL10-dependent interference with neo-angiogenesis. Since Pyk2-KO mice show no life-threatening phenotype, Pyk2 may be a promising therapeutic molecular target for KD.

19. STIM1-induced Ca(2+) signaling activates Pyk2 to inhibit the interaction of VE-PTP and VE-cadherin and hence increase endothelial permeability.

Upon formation of male and female pronuclei, Pyk2 and its activated form accumulate in the two pronuclei. Pyk2 was in blastomere nuclei and the pre-blastula cytoplasm. Pyk2 and its activated form then localized to the perinuclear regions, where blastula cells come into contact with each other.
