Which of the following receptors is a nuclear receptor of the homo-dimeric family?
| a. |
Vitamin D receptor |
|
| b. |
Retinoic acid receptor |
|
| c. |
Glucocorticoid Receptor |
|
| d. |
Thyroid Hormone Receptor |
Homework Answers
These all receptors are nuclear receptor but Glucocorticoid receptor is in homodimer family.
When Glucocorticoid binds to the receptor then the receptor become homodimer form. This homodimer then enter into the nucleus and gene expression occurs.
