Finally, the proposal has been raised by our group [174, 175] and others [138, 142, 176] that DGP-associated proteins, such as POMGNT1, fukutin and FKRP, could act (abnormally) inside the nucleus of tumor cells to glycosylate yet-to-identify proteins with a role in cell proliferation, adhesion and/or migration, including intranuclear signaling proteins and transcription factors, thereby modulating their function. Here, FKTN is linked to neoplasm.
