Structural basis for simultaneous binding of two carboxy-terminal peptides of plant glutamate decarboxylase to calmodulin.
Activation of glutamate decarboxylase (GAD) by calcium-bound calmodulin (CaM) is required for normal plant growth through regulation of gamma-aminobutyrate and glutamate metabolism. The interaction of CaM with the C-terminal domain of GAD is believed to induce dimerization of the enzyme, an event implicated for Ca(2+)-dependent enzyme activation. Here, we present the solution structure of CaM i...
متن کاملGenetic analysis of the carboxy-terminal region of the hepatitis C virus core protein.
Hepatitis C virus (HCV) is a liver-tropic pathogen with severe health consequences for infected individuals. Chronic HCV infection can progress to cirrhosis and hepatocellular carcinoma and is a leading indicator for liver transplantation. The HCV core protein is an essential component of the infectious virus particle, but many aspects of its role remain undefined. The C-terminal region of the ...
متن کاملThe scaffold protein Homer1b/c links metabotropic glutamate receptor 5 to extracellular signal-regulated protein kinase cascades in neurons.
Group I metabotropic glutamate receptors (mGluRs) increase cellular levels of inositol-1,4,5-triphosphate (IP3) and thereby trigger intracellular Ca2+ release. Also, group I mGluRs are organized with members of Homer scaffold proteins into multiprotein complexes involved in postreceptor signaling. In this study, we investigated the relative importance of the IP3/Ca2+ signaling and novel Homer p...
متن کاملThe glutamate receptor of the Qp-type activates protein kinase C and is regulated by protein kinase C.
In striatal neurons in primary culture quisqualate potently stimulated the formation of inositol phosphates via a metabotropic receptor we recently termed Qp in order to distinguish it from the classical ionotropic quisqualate receptor termed Qi. Here we show that 10 microM of quisqualate activated in a rapid and transient manner protein kinase C as assessed by its translocation from the cytoso...
متن کاملFunctional analysis of carboxy-terminal deletion mutants of c-Myb.
The c-myb gene is implicated in the differentiation and proliferation of hematopoietic cells. Truncations of the N and/or C terminus of c-Myb, found in v-Myb, can potentiate its transforming ability. Two negative regulatory subregions, located in the C terminus, were mapped previously by using GAL4-c-Myb fusion proteins in transient transfection assays for the transcriptional activation of a GA...
