POMC : proopiomelanocortin
Description
The POMC (Pro-opiomelanocortin) gene is a crucial player in the intricate symphony of human physiology. This gene resides on chromosome 2 and houses the blueprint for a precursor protein, pro-opiomelanocortin, which undergoes a series of intricate cleavages to yield a diverse array of bioactive peptides. These peptides, including adrenocorticotropic hormone (ACTH), β-endorphin, and melanocyte-stimulating hormone (MSH), orchestrate a range of vital functions, from stress response and energy regulation to pigmentation and appetite control.
Associated Diseases
- **Obesity:** Mutations in POMC can disrupt appetite regulation, leading to increased food intake and weight gain.
- **Adrenocorticotropic Hormone (ACTH) Deficiency:** Impaired POMC function can result in insufficient ACTH production, affecting the body‘s stress response.
- **Red Hair and Fair Skin:** Variations in POMC can influence the production of MSH, impacting pigmentation and leading to lighter skin and hair color.
- **Cushing‘s Disease:** Overproduction of ACTH due to POMC gene abnormalities can cause Cushing‘s disease, characterized by elevated cortisol levels.
