Requirements for PKC-augmented JNK activation by MKK4/7
(Elsevier, 2008)
The c-Jun N-terminal kinases (JNKs) are activated in response to stress, DNA damage, and cytokines by MKK4 and MKK7. We recently demonstrated that PKC can augment the degree of JNK activation by phosphorylating JNK, which ...
Effect of light and protein phosphorylation on photoreceptor rod outer segment acyltransferase activity
(Elsevier Science Inc, 2002-07-01)
Rod outer segments (ROS) exhibit high acyltransferase (AT) activity, the preferred substrate of which being lysophosphatidylcholine. To study factors possibly regulating ROS AT activity purified ROS membranes were assayed ...

Nucleic acids can regulate the activity of casein kinase II
(1989)
Casein kinase II purified from nuclei of Xenopus laevis oocytes is inhibited by several specific nucleic acids. This kinase, the main phosphorylating activity of the oocyte nucleus, is markedly inhibited by poly U at 10 ...
