Ligand-dependent down-regulation leading to fast and extensive lack of protein can
Ligand-dependent down-regulation leading to fast and extensive lack of protein can be characteristic of many nuclear steroid receptors, including individual progesterone receptors (PRs). Particularly, down-regulation of mature PRs happens by a system where ligand binding activates PR phosphorylation by MAPKs at a distinctive serine residue, which in turn focuses on the receptors for degradation. Advanced-stage … [Read more…]
