What is an angiotensin receptor?

Angiotensin receptor is a protein found in the human body that responds to angiotensin hormone like its ligand or key. There are four different types of angiotensin receptors, and each has a slightly different effect on the human body system. The A1 receptor is the most famous and perfect angiotensin receptor. It plays a major role in the Renin-English system in the body (RAS), which is the main regulator of blood pressure and fluid levels in the body. A2 is involved in the cell differentiation process in the fetus and newborn and the specific effects of A3-A4 receptors is less known.

Angiotensin has two forms, type I and type II. Although a certain effect has been observed since the first type, most of the effect that takes place in the receptor places is in response to angiotensin II. Angiotensin receptor is a receptor associated with protein, which means it has a protein that works specifically for the transmission of a chemical signal between cells. As angiotensin II reacts at the site of protein A1, the cascade of physiologicalH processes that affect cellular communication and help maintain homeostasis in multiple organ systems, the most important, circulatory and renal system through races. The A2 receptor is essential for communication between the cells when the fetus develops inside the womb, and any division of communication with angiotensin II can lead to major congenital defects.

RAS is constantly in the flow, because fluids and blood levels move up and down in the body systems, and angiotensin receptors play a major role in maintaining healthy homeostasis. Renin, a free angiotensin hormone, causes blood vessels to reduce, causing increased blood pressure. Angiotensin II in turn causes dilatation of blood vessels. Dehydration and certain conditions, such as diabetes, can cause imbalances in the tounge leading to high blood pressure, excessive thirst and excessive urination. RAS plays an important role in the restoration of balance and maintaining a livingVota, when one loses a significant volume of blood, such as what is experienced with bleeding.

The

cascade of physiological processes that occur after the activation of the angiotensin receptor involves the catalysis of enzymes and other hormones. Tyrosine kinase, enzyme, carries a phosphate group from ATP, which transmits to the receiving protein in a cell, which then acts as an "OFF/ON" switch for cellular processes. Aldosterone, one of the hormones activated by the process, increases the absorption of sodium and the release of potassium in the kidneys. Maintaining the balance between the two electrolytes is paramount for proper cardiac and renal functioning.
