The function of Ensembl gene identifier ENSG00000163638 (ADAMTS9, ADAM metallopeptidase with thrombospondin type 1 motif 9) is as follows. Cleaves the large aggregating proteoglycans, aggrecan (at the '1838-Glu-|-Ala-1839' site) and versican (at the '1428-Glu-|-Ala-1429' site). Has a protease-independent function in promoting the transport from the endoplasmic reticulum to the Golgi apparatus of a variety of secretory cargos. {ECO:0000269|PubMed:12514189, ECO:0000269|PubMed:22419820}.
