This subsection of the ‘Expression’ section reports the experimentally proven effects of inducers and repressors (usually chemical compounds or environmental factors) on the level of protein (or mRNA) expression (up-regulation, down-regulation, constitutive expression).

Example: Q7XTE8, P29305

Transcriptional regulation by transcription factors or repressors is only rarely described in UniProtKB. In some specific cases, however, we indicate such information without going into details.

Example: Q59385

This subsection does not describe the regulation of activity, which can be found in the subsection ‘Enzyme regulation’ for enzymes, and in other subsections, such as ‘Function’.
