Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B
Proline-rich/Ca2+-activated tyrosine kinase (Pyk2) is a member of the FAK family of non-receptor, proline-rich PTK's. Pyk2 signaling is initiated by a variety of extracellular stimuli including integrin ligation, CD surface marker ligation (e.g., CD3, CD28, TCR, VCAM), bioactive peptides, growth factors, cytokines, chemokines and certain stress stimuli. Pyk2 is involved in the regulation of vesicular transport, osteoclastic bone resorption, modulation of ion channels, T- and B-cell receptor signaling and cell death. Phosphorylation of the catalytic domain activation loop tyrosines 579 and 580 by Src results in maximum activation of Pyk2.
