TMED2 and malignant colon neoplasm: Several TMED genes are expressed in colon cancer cells (data not shown), but little is known of the nature of specific cargoes (Strating & Martens, 2009) or the functions of individual p24 proteins, although there is evidence for roles in development (Denzel et al, 2000) and the regulation of the innate immune response (Doyle et al, 2012).
