👉 In biochemistry, "kallidins" are a class of proteins that play a crucial role in regulating cell signaling pathways. They are found in many types of cells and can be involved in various cellular processes such as signal transduction, protein synthesis, and cell cycle regulation. Kallidins have been shown to modulate the activity of other molecules, which is why they are often referred to as "thermoligands." They can also interact with receptors on the surface of cells,
