Pfam2GOMF: Annotations of Pfam domains by Gene Ontology Molecular...

In dcGOR: Analysis of Ontologies and Protein Domain Annotations

Description

An object of class "Anno" that contains associations between Gene Ontology Molecular Function terms and Pfam domains. This data is prepared based on the Pfam database (see http://pfam.xfam.org) and ftp://ftp.geneontology.org/pub/go/external2go/pfam2go.

Usage

data(Pfam2GOMF)

Value

an object of class Anno. It has slots for "annoData", "termData" and "domainData":

• annoData: a sparse matrix of domains X terms

• termData: variables describing ontology terms (i.e. columns in annoData), including: "ID" (i.e. term ID), "Name" (i.e. term Names), "Namespace" (i.e. term Namespace), and "Distance" (i.e. term Distance to the ontology root)

• domainData: variables describing domains (i.e. rows in annoData), including: "id" for Pfam accession ID, and "level" always equals "Pfam", "description" for Pfam description
