DCAF17, DDB1- and CUL4-associated factor 17, is a family of proteins found in eukaryotes. It may function as a substrate-receptor for CUL4-DDB1 E3 ubiquitin-protein ligase complex [1]. Mutations in the human protein, otherwise known as C2orf37, are responsible for Woodhouse-Sakati Syndrome. Woodhouse-Sakati Syndrome is a rare autosomal recessive multi-systemic disorder characterised by hypogonadism, alopecia, diabetes mellitus, mental retardation, and extrapyramidal syndrome [2].

1: A family of diverse Cul4-Ddb1-interacting proteins includes Cdt2, which is required for S phase destruction of the replication factor Cdt1. Jin J, Arias EE, Chen J, Harper JW, Walter JC; Mol Cell. 2006;23:709-721. PMID:16949367

2: Mutations in C2orf37, encoding a nucleolar protein, cause hypogonadism, alopecia, diabetes mellitus, mental retardation, and extrapyramidal syndrome.
