Members of this family are involved in various cellular processes like cell proliferation and death, cell motility and metabolic pathways. In this contribution we shall review the available structural biology data on five members of this kinase family (calcium/calmodulin dependent kinase, twitchin kinase, titin kinase, phosphorylase kinase, myosin light chain kinase). As a common element, all these kinases contain a regulatory tail, which is C-terminal to their catalytic domain. The available 3D structures of two members, the serine/threonine kinases of the giant muscle proteins twitchin and titin in the autoinhibited conformation, show how this regulatory tail blocks their active sites. The structures suggest that activation of these kinases requires unblocking the active site from the C-terminal extension and conformational rearrangement of the active site loops. Small angle scattering data for myosin light chain kinase indicate a complete release of the C-terminal extension upon calcium/calmodulin binding. In addition, members of this family are regulated by diverse add-on mechanisms, including phosphorylation of residues within the activation segment or the P+1 loop as well as by additional regulatory subunits. The available structural data lead to the hypothesis of two different activation mechanisms upon binding to calcium sensitive proteins. In one model, the regulatory tail is entirely released ("fall-apart"). The alternative model ("looping-out") proposes a two-anchored release mechanism.</dcterms:abstract> <dc:contributor>Wilmanns, Matthias</dc:contributor> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dc:creator>Wilmanns, Matthias</dc:creator> <dc:contributor>Mayans, Olga</dc:contributor> <dc:creator>Mayans, Olga</dc:creator> <dc:contributor>Gautel, Mathias</dc:contributor> <dcterms:issued>2000</dcterms:issued> <dc:language>eng</dc:language> <dcterms:title>Activation of calcium/calmodulin regulated kinases</dcterms:title> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dcterms:rights rdf:resource="https://rightsstatements.org/page/InC/1.0/"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2021-01-18T07:46:19Z</dc:date> <dc:rights>terms-of-use</dc:rights> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/52479"/> <dc:creator>Gautel, Mathias</dc:creator> </rdf:Description> </rdf:RDF>
