Genomic Relationships

These relationship types link related terms, like orthologous terms from two different species or the geneAbundance() and rnaAbundance() terms for the same namespace value.

In most cases, these relationships will be introduced by the BEL Namespace resources, and are not needed for creation of BEL Statements and BEL Documents.


For terms A and B, A orthologous B indicates that A and B represent entities in different species which are sequence similar and which are therefore presumed to share a common ancestor. For example,

g(hgnc:391 ! AKT1) orthologous g(mgi:87986 ! Akt1)

indicates that the mouse and human AKT1 genes are orthologs.


For RNA abundance term R and gene abundance term G, G transcribedTo R or G :> R indicates that members of R are produced by the transcription of members of G. For example:

g(hgnc:391 ! AKT1) :> r(hgnc:391 ! AKT1)

indicates that the human AKT1 RNA is transcribed from the human AKT1 gene.


For RNA abundance term R and protein abundance term P, R translatedTo P or R P indicates that members of P are produced by the translation of members of R. For example:

# long form
r(HGNC:AKT1) translatedTo p(HGNC:AKT1)

# short form
r(HGNC:AKT1) >> p(HGNC:AKT1)
