Sulfated proteoglycans have important structural and signaling functions in the growth plate. In the October 1, 2008, issue of Genes & Development, Settembre and colleagues (pp. 2645 - 2650) report that lack of SUMF1, a crucial enzyme in the activation of sulfatases, causes a severe chondrodysplasia by augmenting fibroblast growth factor signaling and by hampering the autophagic process, which the investigators show is constitutively on in chondrocytes. The findings highlight the essential role of desulfation in cartilage biology and organogenesis.
