Nascent-polypeptide-associated complex (NACA) binds to newly created polypeptides to prevent wrong translocation to the endoplasmatic reticulum and plays a role in bone formation and red blood cell differentiation and has been linked to dermatitis (Lauring et al. 1995; Natter et al. 1998; Lopez et al. 2005). Here, NACA is linked to dermatitis.
