What is the reaction product excitation/emission maxima when using the EnzChek Phosphatase Assay kit?
The reaction product has excitation/emission maxima of approximately 358/455 nm. Fluorescence can be measured in a fluorescence microplate reader or a standard fluorometer.
Plectin scaffolds recruit energy-controlling AMP-activated protein kinase (AMPK) in differentiated myofibres.

'Plectin, a cytolinker protein greater than 500 kDa in size, has an important role as a mechanical stabiliser of cells. It interlinks the various cytoskeletal filament systems and anchors intermediate filaments to peripheral junctional complexes. In addition, there is increasing evidence that plectin acts as a scaffolding platform that controls ... More
The Down syndrome critical region protein RCAN1 regulates long-term potentiation and memory via inhibition of phosphatase signaling.

'Regulator of calcineurin 1 (RCAN1/MCIP1/DSCR1) regulates the calmodulin-dependent phosphatase calcineurin. Because it is located on human chromosome 21, RCAN1 has been postulated to contribute to mental retardation in Down syndrome and has been reported to be associated with neuronal degeneration in Alzheimer''s disease. The studies herein are the first to ... More
Adenovirus-facilitated nuclear translocation of adeno-associated virus type 2.

Journal:J Virol
PubMed ID:12388712
'We examined cytoplasmic trafficking and nuclear translocation of adeno-associated virus type 2 (AAV) by using Alexa Fluor 488-conjugated wild-type AAV, A20 monoclonal antibody immunocytochemistry, and subcellular fractionation techniques followed by DNA hybridization. Our results indicated that in the absence of adenovirus (Ad), AAV enters the cell rapidly and escapes from ... More
Redox modulation of global phosphatase activity and protein phosphorylation in intact skeletal muscle.
Authors:Wright VP, Reiser PJ, Clanton TL,
Journal:J Physiol
PubMed ID:19841000
Skeletal muscles produce transient reactive oxygen species (ROS) in response to intense stimulation, disuse atrophy, heat stress, hypoxia, osmotic stress, stretch and cell receptor activation. The physiological significance is not well understood. Protein phosphatases (PPases) are known to be highly sensitive to oxidants and could contribute to many different signalling ... More
