'''Collagen alpha-5(VI) chain''' also known as '''von Willebrand factor A domain-containing protein 4''' is a protein that in humans is encoded by the COL6A5 gene.
COL6A5 is a part of the Collagen VI gene family which produce collagen components for the Extracellular matrix of most connective tissues.<ref name=Fitzgerald>{{cite journal | vauthors = Fitzgerald J, Holden P, Hansen U | title = The expanded collagen VI family: new chains and new questions | journal = Connective Tissue Research | volume = 54 | issue = 6 | pages = 345–50 | date = 2013 | pmid = 23869615 | doi = 10.3109/03008207.2013.822865 | url = http://journals2.scholarsportal.info/pdf/03008207/v54i0006/345_tecvfncanq.xml | pmc=5248970}}</ref> In the human genome, part of the collagen VI family is located on chromosome 3q in order of COL6A4, COL6A5, COL6A6.<ref name=Fitzgerald /> Transcription of COL6A5 only occurs in skin, lung, testis, colon, and small intestine cells.<ref name=Fitzgerald />
