Post-transcriptional regulation
Regulation of gene expression after the gene has been transcribed into mRNA. For example, by regulation of translation, regulation of protein activity, or regulation of protein turnover.

We know that the receptors, the proteins themselves that are modified, only last a few days, so they will actually turnover--that is, they will be broken down, degraded, and new ones will replace those receptors.
