calcineurin (can) is a ca2+/calmodulin (ca2+/cam)-dependent serine/threonine protein phosphatase expressed in most mammalian tissues but found at higher concentration in brain. in the last decade there have been a steadily increasing number of studies identifying neuronal can as a primary suspect in neuronal vulnerability, synapse loss, dendritic atrophy, synaptic dysfunction and neuroinflammat...

Calcineurin, which functions in calcium signaling, is expressed in skeletal and cardiac muscle and has been linked to sensitivity to muscle strength training. It is also proposed to contribute to individual aerobic endurance. To investigate the relationship between calcineurin-encoding genes and aerobic endurance traits, 126 young-adult Han Chinese males were enrolled in an aerobic exercise tra...

Transcription factors belonging to the nuclear factor of activated T cells (NFAT) family regulate the expression of cytokine genes and other inducible genes during the immune response. The functions of NFAT proteins are directly controlled by the calcium- and calmodulin-dependent phosphatase calcineurin. Here we show that the binding of calcineurin to NFAT is substantially increased when calcin...

Calcineurin signaling plays diverse roles in fungi in regulating stress responses, morphogenesis and pathogenesis. Although calcineurin signaling is conserved among fungi, recent studies indicate important divergences in calcineurin-dependent cellular functions among different human fungal pathogens. Fungal pathogens utilize the calcineurin pathway to effectively survive the host environment an...

The calcineurin inhibitors cyclosporine A (CsA) and tacrolimus are widely used in the treatment of proteinuria diseases. As the direct target of these drugs, calcineurin has previously been demonstrated to play a role in proteinuria diseases. However, aside from its immune-related effects, the local status of calcineurin in renal inherent cells has not been fully explored in the settings of pro...

Calcineurin is a highly conserved Ca2+/calmodulin-dependent serine/threonine-specific protein phosphatase that orchestrates cellular Ca2+ signaling responses. In Cryptococcus neoformans, calcineurin is activated by multiple stresses including high temperature, and is essential for stress adaptation and virulence. The transcription factor Crz1 is a major calcineurin effector in Saccharomyces cer...

Calcineurin governs stress survival, sexual differentiation, and virulence of the human fungal pathogen Cryptococcus neoformans. Calcineurin is activated by increased Ca2+ levels caused by stress, and transduces signals by dephosphorylating protein substrates. Herein, we identified and characterized calcineurin substrates in C. neoformans by employing phosphoproteomic TiO2 enrichment and quanti...

Excessive immune responses induced by ischemia-reperfusion injury (IRI) are known to lead to necrotic and apoptotic cell death, and calcineurin plays a major role in this process. Calcineurin dephosphorylates the nuclear factor of activated T-cells (NFAT), permitting its translocation into the nucleus. As a result, calcineurin promotes the release of pro-inflammatory cytokines, such as tumor ne...

Calcineurin phosphatase plays a crucial role in T cell activation. Dephosphorylation of the nuclear factors of activated T cells (NFATs) by calcineurin is essential for activating cytokine gene expression and, consequently, the immune response. Current immunosuppressive protocols are based mainly on calcineurin inhibitors, cyclosporine A and FK506. Unfortunately, these drugs are associated with...
