Cartilage-specific ablation of site-1 protease in mice results in the endoplasmic reticulum entrapment of type IIb procollagen and down-regulation of cholesterol and lipid homeostasis.

Cartilage-specific ablation of site-1 protease in mice results in the endoplasmic reticulum entrapment of type IIb procollagen and down-regulation of cholesterol and lipid homeostasis.

The proprotein convertase site-1 protease (S1P) converts latent ER-membrane bound transcription factors SREBPs and ATF6 to their active forms. SREBPs are involved in cholesterol and fatty acid homeostasis whereas ATF6 is involved in unfolded protein response pathways (UPR). Cartilage-specific ablati...
