protein overexpression model

Accession MO:0000032
DefinitionThis model detects protein overexpression based on the presence of mutations. The detection of the protein without an associated mutation indicates that the protein is likely to be expressed at low or basal levels. The detection of the protein with the mutation indicates that the protein is likely overexpressed. This model reflects how certain proteins are functional with and without mutations. For example, efflux pump subunits and regulators are functional with mutations and without mutations. Without mutations, efflux pump subunits and regulators are usually expressed at a low level. When an efflux pump regulator has a mutation, it can cause the overexpression of the efflux pump it is responsible for regulating, leading to resistance to specific drugs. Protein overexpression models have two parameters: a curated BLASTP cutoff, and a curated set of mutations (single resistance variants, frameshift mutations, indels, etc.) shown clinically to confer resistance. This model type is a combination of the protein homolog and protein variant model. A detected hit can be categorized as Perfect, Strict, or Loose with no mutation(s) or as Strict or Loose with mutation(s).
