Ski/Dach domain-containing protein 1 is a protein that in humans is encoded by the SKIDA1 gene. It is also known as C10orf140 and DLN-1. It has orthologs in vertebrates. It has two domains: the Ski/Sno/Dac domain and a domain of unknown function, DUF4854. It is associated with multiple types of cancer, like leukemia, ovarian cancer, and colon cancer. It's predicted to be a nuclear protein. It may interact with PRC2.
