This subclass of ID describes external database references to the joint project between EMBL - European Bioinformatics Institute (EBI) and the Wellcome Trust Sanger Institute (WTSI) to develop a software system which produces and maintains automatic annotation on selected eukaryotic proteomes.
This subclass of SingleProcedure describes a process whereby a metal tube is inserted into the body to draw off fluid or to introduce medication.
This subclass of AlphaSubunit is the subunit that is part of the potassium channel comple and is know to have six transmembrane segments, homologous to a single domain of the sodium channels. Correspondingly, they assemble as tetramers to produce a functioning channel and have a distinctive pore-loop structure that lines the top of the pore and is responsible for potassium selectivity.

This subclass of BetaSubunit describes a sodium channel subunit that when assembled with alpha subunits the resulting complex can display altered voltage dependence and cellular localization

This subclass of ElectronMicroscope is a microscope that uses a beam of electrons is transmitted through a specimen, then an image is formed, magnified and directed to appear either on a fluorescent screen or layer of photographic film, or to be detected by a sensor such as a CCD camera. Also known as TEM, the transmission electrons are what are being detected.
This subclass of IonCurrent is the variable used for measuring the sodium-potassium pump current
This subclass of Gene describes genes that encode for sodium channel subunits.

This subclass of Device describes a solid electric conductor through which an electric current enters or leaves an electrolytic cell or other medium.
This subclass of IonCurrent is the variable used for measuring inwardly rectifing potassium current.
This subclass of IonCurrent describes current measurements acquired from ion channels/ transporters, that have been created by the artificial insertion of DNA into existing DNA coding stands, creating a "man-made" form of a gene that encodes the particular ion channel or transporter

This subclass of BetaSubunit describes the calcium channel subunit that is situated intracellularly and is involved in the membrane trafficking of alpha 1subunits

This subclass of Electrode describes an electrode that traditionally uses a glass pipette, with an open tip diameter of about one micrometre, and is made such that the tip forms a smooth surfaced circle, rather than a sharp point.

This subclass of GammaSubunit is has been described since 1978 and to this date can be found in complexes with both the alpha and beta subunits of the sodium potassium pump complex, but yet to date not much is known about it.
This subclass of ATPDependentCalciumPump describes a class of ion pump that uses ATP to pump Ca2+ ions across the sarcoplasmic reticulum (SR)
