Although the messenger RNA transcript encoding this protein was initially named DOC2 (for Differentially expressed in Ovarian Cancer) because it was differentially expressed in ovarian cancer, the protein is now referred to as Disabled homolog-2 or Dab2 as it is transcribed from an ortholog of the Drosophila Dab gene (Gertler et al., 1989). Here, DAB2 is linked to ovarian carcinoma.
