Since then, many LTPs have been isolated from bacteria, plants, yeast, and mammals, and extensively studied in cell-free systems and intact cells. A major advance in the LTP field was associated with the discovery of intracellular membrane contact sites (MCSs), small cytosolic gaps between Edited by: the endoplasmic reticulum (ER) and other cellular membranes, which accelerate lipid Mitsuo Tagaya, transfer by LTPs. As LTPs modulate the distribution of lipids within cellular membranes, Tokyo University of Pharmacy and Life and many lipid species function as second messengers in key signaling pathways that Sciences, Japan control cell survival, proliferation, and migration, LTPs have been implicated in cancer- Reviewed by: Tamas Balla, associated signal transduction cascades. Increasing evidence suggests that LTPs play National Institutes of Health (NIH), an important role in cancer progression and metastasis. This review describes how United States Thomas Simmen, different LTPs as well as MCSs can contribute to cell transformation and malignant University of Alberta, Canada phenotype, and discusses how “aberrant” MCSs are associated with tumorigenesis *Correspondence: in human.
