Indicadores
5'-nucleotidase (574 aa, ~63 kDa) is encoded by the human NT5E gene. This protein is involved in the conversion of nucleotides to nucleosides.
Pruebas

Indicadores
A family of phosphatases that add monophosphates to substrates. The optimal pH for activity of these enzymes is below 7.
Indicadores
This gene is involved in signal transduction and the inhibition of apoptosis.
Indicadores
The orally bioavailable alpha form of the naturally-occurring fat-soluble vitamin E, with potent antioxidant and cytoprotective activities. Upon administration, alpha-tocopherol neutralizes free radicals, thereby protecting tissues and organs from oxidative damage. Alpha-tocopherol gets incorporated into biological membranes, prevents protein oxidation and inhibits lipid peroxidation, thereby maintaining cell membrane integrity and protecting the cell against damage. In addition, alpha-tocopherol inhibits the activity of protein kinase C (PKC) and PKC-mediated pathways. Alpha-tocopherol also modulates the expression of various genes, plays a key role in neurological function, inhibits platelet aggregation and enhances vasodilation. Compared with other forms of tocopherol, alpha-tocopherol is the most biologically active form and is the form that is preferentially absorbed and retained in the body.
Indicadores
