Cоrtisоl is а signаling mоlecule thаt regulates gene expression in the cells of a mammal. Cortisol enters a cell and binds to a protein called a cortisol receptor. Binding of cortisol facilitates the phosphorylation of the cortisol receptor, which then can enter the nucleus and affect transcription. The figure below shows a system of two genes whose transcription is regulated by cortisol. The IL10 gene codes for a protein called interleukin 10. The BGLAP gene codes for a protein called osteocalcin. A cortisol receptor can activate or repress the transcription of a gene by binding to a regulatory element. For example, a cortisol receptor activates transcription of the IL10 gene but represses transcription of the BGLAP gene. When a person experiences stress, their adrenal gland releases cortisol, increasing the concentration of cortisol throughout the body. As a person sleeps, the concentration of cortisol in their blood decreases to nearly zero. After waking, the concentration of cortisol increases by four to seven times the concentration during sleep. Complete the following sentence. During sleep, a cortisol receptor is _______ to be bound to the regulatory element of the IL10 gene.
