aitavad seostada kollageeni fibrille omavahel ja ka teiste rakuvälise maatrikis komponentidega, määrates sel viisil fibrillide paigutuse maatriksis, These collagens help to bind collagen fibrils to each other and to other extracellular matrix components, determing fibril location in matrix. These collagens, including IX and XII are flexible and have helical (including 3 fibers) structure, favor binding on fibrils survace rather to form agregates.
