Functions
3 GO annotations of cellular component
Name | Definition |
---|---|
cAMP-dependent protein kinase complex | An enzyme complex, composed of regulatory and catalytic subunits, that catalyzes protein phosphorylation. Inactive forms of the enzyme have two regulatory chains and two catalytic chains; activation by cAMP produces two active catalytic monomers and a regulatory dimer. |
cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
plasma membrane | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
2 GO annotations of molecular function
Name | Definition |
---|---|
cAMP binding | Binding to cAMP, the nucleotide cyclic AMP (adenosine 3',5'-cyclophosphate). |
cAMP-dependent protein kinase regulator activity | Modulation of the activity of the enzyme cAMP-dependent protein kinase. |
1 GO annotations of biological process
Name | Definition |
---|---|
regulation of protein phosphorylation | Any process that modulates the frequency, rate or extent of addition of phosphate groups into an amino acid in a protein. |
