Progestin and adipoQ receptor

From WikiMD's Wellnesspedia

Progestin and adipoQ receptor‏‎ (PAQR) is a family of proteins that are involved in a variety of biological processes. The family includes several members, such as Adiponectin receptor 1 (AdipoR1), Adiponectin receptor 2 (AdipoR2), and Progestin and adipoQ receptor 7 (PAQR7), among others.

Function[edit | edit source]

PAQR proteins are primarily known for their role in metabolism and endocrine regulation. They are named for their ability to bind to progestin, a type of steroid hormone, and adiponectin, a hormone that regulates glucose levels and fatty acid breakdown.

AdipoR1 and AdipoR2, for example, are integral membrane proteins that serve as receptors for adiponectin, an important hormone in the regulation of glucose and lipid metabolism. These receptors play a crucial role in maintaining energy homeostasis and insulin sensitivity.

Structure[edit | edit source]

PAQR proteins are characterized by their seven-transmembrane domain structure, which is a common feature of G protein-coupled receptors (GPCRs). However, unlike traditional GPCRs, PAQR proteins are thought to signal through a different mechanism, although the exact details of this process are still under investigation.

Clinical significance[edit | edit source]

Alterations in the function of PAQR proteins have been linked to a variety of health conditions. For instance, mutations in AdipoR1 and AdipoR2 have been associated with insulin resistance and type 2 diabetes. Additionally, some studies suggest that PAQR proteins may play a role in cancer progression, although more research is needed to fully understand these potential connections.
