Gene expression regulation
Gene expression depends on chromatin accessibility, transcription-factor binding, RNA processing, transcript stability and translation. Regulation differs across tissues and development.

Chromatin
DNA packaging and modifications influence whether regulatory proteins can access promoter and enhancer regions.
Transcription
Transcription factors and RNA polymerase cooperate with regulatory DNA and cofactors to produce primary RNA transcripts.
RNA processing
Splicing, capping, polyadenylation and transcript turnover influence which mature mRNA isoforms are available.
Translation and protein fate
Ribosome activity, post-translational modifications and protein degradation shape functional protein abundance independently of mRNA level.
