Type III collagen often interacts with other types of collagen, particularly type I collagen, to form complex networks that provide mechanical support to tissues. In many connective tissues, type III collagen is found alongside type I collagen, where it helps to regulate the diameter of type I collagen fibrils and contributes to the overall mechanical properties of the tissue. This interaction is crucial for the proper function of tissues such as the skin, blood vessels, and internal organs.
