REGULATION OF GENE EXPRESSION Gene Regulatory transcription factors can activate or inhibit transcription. The arrangements and composition of nucleosomes influence transcription. DNA methylation (usually) inhibits transcription. Transcription pre-MRNA RNA processing Alternative splicing alters exon choices. RNA editing alters the base sequence of mRNAs. MRNA Small RNAS, called miRNAs and siRNAs, silence the translation of MRNA, a process called RNA interference. Translation Proteins that bind to the 5' end of MRNA regulate translation. MRNA stability may be influenced by RNA-binding proteins. Protein Posttranslatlonal modificatlons Feedback inhibition and covalent modifications regulate protein function.
