Stress signaling through Ca2+/calmodulin-dependent protein phosphatase calcineurin mediates salt adaptation in plants.
Calcineurin (CaN) is a Ca2+- and calmodulin-dependent protein phosphatase (PP2B) that, in yeast, is an integral intermediate of a salt-stress signal transduction pathway that effects NaCl tolerance through the regulation of Na+ influx and efflux. A truncated form of the catalytic subunit and the regulatory subunit of yeast CaN were coexpressed in transgenic tobacco plants to reconstitute a cons...
متن کاملA signaling complex of Ca2+-calmodulin-dependent protein kinase IV and protein phosphatase 2A.
Stimulation of T lymphocytes results in a rapid increase in intracellular calcium concentration ([Ca2+]i) that parallels the activation of Ca2+-calmodulin-dependent protein kinase IV (CaMKIV), a nuclear enzyme that can phosphorylate and activate the cyclic adenosine monophosphate (cAMP) response element-binding protein (CREB). However, inactivation of CaMKIV occurs despite the sustained increas...
متن کاملThe Ca /Calmodulin-dependent Protein Kinase Kinases Are AMP-activated Protein Kinase Kinases*□S
The AMP-activated protein kinase (AMPK) is an important regulator of cellular metabolism in response to metabolic stress and to other regulatory signals. AMPK activity is absolutely dependent upon phosphorylation of AMPK Thr-172 in its activation loop by one or more AMPK kinases (AMPKKs). The tumor suppressor kinase, LKB1, is a major AMPKK present in a variety of tissues and cells, but several ...
متن کاملCa2+/Calmodulin-Dependent Protein Kinase Kinases (CaMKKs) Effects on AMP-Activated Protein Kinase (AMPK) Regulation of Chicken Sperm Functions
Sperm require high levels of energy to ensure motility and acrosome reaction (AR) accomplishment. The AMP-activated protein kinase (AMPK) has been demonstrated to be strongly involved in the control of these properties. We address here the question of the potential role of calcium mobilization on AMPK activation and function in chicken sperm through the Ca(2+)/calmodulin-dependent protein kinas...
متن کاملRegulatory cascades involving calmodulin-dependent protein kinases.
Elucidation of the components that comprise signaling cascades in cells is a primary theme in molecular endocrinology. These signal transduction pathways are frequently initiated at the plasma membrane by the interaction of a ligand with a cell surface receptor. This interaction can result in activation of a number of pathways that are initiated by stimulation of signaling proteins such as JAK/...
