A multisubunit tethering complex, i.e. a protein complex involved in mediating the initial interaction between vesicles and the membranes with which they fuse, that is involved in trafficking from the Golgi apparatus to the ER. In Saccharomyces cerevisiae the Dsl1p complex contains Dsl1p, Tip20p, and Sec39p. [ http://www.ncbi.nlm.nih.gov/pubmed/19151722 http://www.ncbi.nlm.nih.gov/pubmed/21550981 ]
