The proline rich tyrosine kinase 2 (PYK2) is a nonreceptor protein tyrosine kinase that is structurally related to FAK and thought to be important for leukocyte activation (Ostergaard & Lysechko, 2005). PYK2 tyrosine phosphorlation is known to occur downstream of IL-2 stimulation in human peripheral T lymphocytes. This phosphorylation can be prevented by blocking IL-2 mediated JAK activity. Although the function of Pyk2 within the IL-2 signaling pathways remains uncertain, a dominant negative mutant of Pyk2 inhibited IL-2-induced cell proliferation without affecting Stat5 activation which suggests that Pyk2 does indeed influence IL-2 driven immune cell responses.
