rxn() function expresses the transformation of products into reactants, each defined by a list of abundances. For example:
This BEL Term represents the reaction in which the reactants phosphoenolpyruvate and ADP are converted into pyruvate and ATP.
Translocations, or the movement of abundances from one location to another, are represented in BEL Terms by the
tloc() function. For convenience, the frequently used translocations of abundances from inside the cell to cell surface or extracellular space are represented by the
cellSecretion() functions, respectively. The following term represents the event in which human NFE2L2 protein is translocated from the cytoplasm to the nucleus:
translocation() function requires arguments for both the starting and ending locations.
In cases where the starting location is not known, but is within the cell, the general MeSH term "Intracellular Space" can be used. For example:
Secretion of mouse IL6 protein can be represented by:
Cell surface expression of rat Fas can be represented by:
Events in which an abundance is degraded can be represented by the
deg() function. For example:
This term represents the degradation of the human MYC RNA. Degradation decreases the amount of the abundance - when degradation statements are compiled, a directlyDecreases relationship edge is added between the degradation term and the degraded entity.
