SCAMP3 and cancer: Whether these molecular partners, such as SEC23IP (protein transport protein Sec23A-interacting protein), SCAMP3 (secretory carrier-associated membrane protein 3), or LITAF (lipopolysaccharide-induced tumor necrosis factor-alpha factor homologue), also known as SIMPLE (small membrane protein of the lysosome/late endosome), are involved in cancer progression has not been completely elucidated.
