We have examined the activity and substrate specificity of the Saccharomyces cerevisiae Hrr25p and the Schizosaccharomyces pombe Hhp1, Hhp2, and Cki1 protein kinase isoforms. These four gene products are isotypes of casein kinase I (CKI), and the sequence of these protein kinases predicts that they are protein serine/threonine kinases. However, each of these four protein kinases, when expressed in Escherichia coli in an active form, was recognized by anti-phosphotyrosine antibodies.

Pancreatic cancer remains one of the most difficult malignancies to treat. Minimal improvements in patient outcomes and persistently abysmal patient survival rates underscore the great need for new treatment strategies. Currently, there is intense interest in therapeutic strategies that target tyrosine protein kinases.

Bruton's tyrosine kinase (Btk) is tyrosine phosphorylated and enzymatically activated following ligation of the B-cell antigen receptor. These events are temporally regulated, and Btk activation follows that of various members of the Src family of protein tyrosine kinases, thus raising the possibility that Src kinases participate in the Btk activation process. We have evaluated the mechanism underlying Btk enzyme activation and have explored the potential regulatory relationship between Btk and Src protein kinases.

Protein tyrosine kinase activity was assayed in a variety of chicken tissues during embryonic development and in the adult. In some tissues protein tyrosine kinase activity decreased during embryonic development; however, in other tissues it remained high throughout development, it contrast to the level of protein tyrosine phosphorylation, which decreased during development. The highest levels of tyrosine kinase activity were detected in 17-d embryonic brain although only low levels of protein tyrosine phosphorylation were observed in this tissue. Several alternatives were examined in an effor

Abstract Protein tyrosine phosphorylations are involved in the proliferation and secretory responses of immune cells, but their role in phagocytes is poorly understood. The ability of unopsonized zymosan to induce protein tyrosine phosphorylations was investigated in human monocytes. The addition of zymosan to monocytes resulted in an increase in tyrosine phosphorylation of several endogenous proteins including 28-, 33-, 38-, 42-, 47-, 55- to 60-, 62-, 68-, 90-, 105-, 116-, and 120-kDa proteins; 55- to 60-kDa proteins were the predominant phosphoproteins.

Two separate signal transduction pathways exist in vascular smooth muscle: one for cell growth, proliferation, and differentiation and the other for contraction. Although activation of protein tyrosine kinases is intimately involved in the signaling pathway that induces cell growth, proliferation, and differentiation, activation of myosin light chain kinase (MLCK) is an important step in the pathway leading to smooth muscle contraction. Indirect evidence suggests that “cross talk” exists between these two signaling pathways, but the common intermediates are not well defined. The purpose of thi

This function requires not only the kinase domain of Csk, but also its Src homology 3 (SH3) and SH2 regions. We showed previously that the Csk SH3 domain mediates highly specific associations with two members of the PEP family of nonreceptor protein tyrosine phosphatases (PTPs), PEP and PTP-PEST.
