4 GO annotations of cellular component

Name Definition
bicellular tight junction An occluding cell-cell junction that is composed of a branching network of sealing strands that completely encircles the apical end of each cell in an epithelial sheet; the outer leaflets of the two interacting plasma membranes are seen to be tightly apposed where sealing strands are present. Each sealing strand is composed of a long row of transmembrane adhesion proteins embedded in each of the two interacting plasma membranes.
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.
membrane A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

6 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.
potassium channel inhibitor activity Binds to and stops, prevents, or reduces the activity of a potassium channel.
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.

14 GO annotations of biological process

Name Definition
cellular cation homeostasis Any process involved in the maintenance of an internal steady state of cations at the level of a cell.
cellular chloride ion homeostasis Any process involved in the maintenance of an internal steady state of chloride ions at the level of a cell.
chloride transport The directed movement of chloride into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
distal tubule morphogenesis The process in which the anatomical structures of a distal tubule are generated and organized. The distal tubule is a nephron tubule that begins at the macula densa and extends to the connecting tubule.
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.
ion transport The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
negative regulation of pancreatic juice secretion Any process that decreases the rate, frequency or extent of pancreatic juice secretion, the regulated release of pancreatic juice by the exocrine pancreas into the upper part of the intestine.
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 localization Any process in which a protein is transported to, or maintained in, a specific location.
protein phosphorylation The process of introducing a phosphate group on to a protein.
renal sodium ion absorption A renal system process in which sodium ions are taken up from the collecting ducts and proximal and distal loops of the nephron. In non-mammalian species, absorption may occur in related structures.
