Collagen alpha-1(XXIII) ectodomains Cleaved collagen type XXIII Collagen type XXIII Collagen type XXIII ectodomain shedding Authored: Jupe, S, 2011-07-12 Collagen type XXIII is a type II transmembrane collagen with a relatively small ectodomain. It exists in a membrane-bound form and a shed form, cleaved by furin (Veit et al. 2007). Both forms can bind alpha2beta1 integrin via the ectodomain, stimulating the formation of focal adhesion plaques (Veit et al. 2011).
