Enzymatic interactions of Ptk2b

  • Pyk2 can be dephosphorylated in vitro in SHP-2 immunoprecipitates and in intact cells expressing an NH(2) terminus-truncated form of SHP-2, which lacks the two SH2 domains but has an enhanced phosphatase activity [22].
 

Regulatory relationships of Ptk2b

  • Inhibition of Pyk2 activation also suppressed Rac1 activation and reactive oxygen species (ROS) production [1].
  • Ang II caused activation of protein kinase C delta (PKCdelta) in C9 cells, and its stimulatory actions on Pyk2 and extracellularly regulated kinase (ERK) phosphorylation were abolished by PKC depletion and selective inhibition of PKCdelta by rottlerin, but not by Ca(2+)-chelators [23].
  • The c-src inhibitor PP1 inhibited carbachol-stimulated phosphorylation of Pyk2 [24].
  • Following ischemia, tyrosine phosphorylation of NR2A and NR2B and activated Src-family kinases (SFKs) and Pyk2 were increased in post-synaptic densities (PSDs) [25].
  • Thus, activating CAKbeta/Pyk2 is required for inducing LTP and may depend upon downstream activation of Src to upregulate NMDA receptors [9].
