Interestingly, Rab37 also exerts tumor suppressive function in cancer epithelial cells (see “Exocytic trafficking of secretory proteins in cancer cells” section), while it functions as a pro-tumor factor in cancer associated immune cells (see “Vesicles trafficking pathways in macrophages” and “Vesicles trafficking pathways in neutrophils” sections). Here, RAB37 is linked to neoplasm.
