The Rab subfamily of small GTPases plays an important role in the regulation of membrane traffic in eukaryotic cells. While most Rab proteins are equally expressed in polarized and nonpolarized cells, Rab17 and Rab18 show epithelial cell specificity. Here we report the genetic mapping of Rab17 and Rab18 on mouse chromosomes 1 and 18, respectively. We also discuss some implications of Rab17 and Rab18 mapping, including their candidacy for the mouse mutations ln (leaden), Tw (twirler), and ax (ataxia).
