2 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

8 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
chloride channel inhibitor activity Binds to and stops, prevents, or reduces the activity of a chloride channel.
phosphatase binding Binding to a phosphatase.
potassium channel inhibitor activity Binds to and stops, prevents, or reduces the activity of a potassium channel.
protein kinase inhibitor activity Binds to and stops, prevents or reduces the activity of a protein kinase, an enzyme which phosphorylates a protein.
protein serine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate.
protein serine/threonine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate.
protein serine/threonine/tyrosine kinase activity Catalysis of the reactions: ATP + a protein serine = ADP + protein serine phosphate; ATP + a protein threonine = ADP + protein threonine phosphate; and ATP + a protein tyrosine = ADP + protein tyrosine phosphate.

6 GO annotations of biological process

Name Definition
intracellular signal transduction The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
ion homeostasis Any process involved in the maintenance of an internal steady state of ions within an organism or cell.
negative regulation of sodium ion transport Any process that decreases the frequency, rate or extent of the directed movement of sodium ions (Na+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
positive regulation of potassium ion import across plasma membrane Any process that activates or increases the frequency, rate or extent of potassium ion import across the plasma membrane.
positive regulation of sodium ion transmembrane transporter activity Any process that activates or increases the frequency, rate or extent of sodium ion transmembrane transporter activity.
protein phosphorylation The process of introducing a phosphate group on to a protein.
