Proto-Oncogenes and Oncogenes, Extended

The idea
Proto-oncogenes and oncogenes are homed at Bio 0895; they illustrate gene-expression regulation failing, not a new definition.
In practice
A proto-oncogene, per Bio 0895, becomes an oncogene when a mutation escapes this unit's regulatory controls and locks its regulator active.
Where people slip
This entry extends Bio 0895 into this unit's regulation framework — it does not relock or restate that definition.
