25186462-2	2014	A distinct feature of DS is the presence of iduronic acid, produced by the two enzymes, DS-epimerase 1 and 2, which are encoded by Dse and Dsel, respectively.	Dermatan Sulfate	22-24	dermatan sulfate epimerase-like	Mus musculus	139-143	
21177331-4	2011	In this study, to clarify the distribution of the DS-type structure in the brain during development, the expression patterns of DS epimerase 1 (DS-epi1) and DS-epi2, both of which convert d-glucuronic acid into IdoA, were investigated by in situ hybridization.

21177331-6	2011	Quantitative real-time polymerase chain reaction revealed the expression of DS-epi2 to be higher than that of DS-epi1 throughout development, suggesting that DS-epi2 but not DS-epi1 is mostly expressed in the brain and plays key roles in the epimerization of CS/DS during its biosynthesis.

19687302-1	2009	Dermatan sulfate epimerase 1 (DS-epi1) and DS-epi2 convert glucuronic acid to iduronic acid in chondroitin/dermatan sulfate biosynthesis.	Dermatan Sulfate	107-123	dermatan sulfate epimerase-like	Mus musculus	43-50
