N-glycosylation-defective splice variants of neuropilin-1 promote metastasis by activating endosomal signals

Abstract

O-glycosylation of neuropilin-1 is involved in cancer migration and invasion. Here, the authors show that defects in N-glycosylation of two neuropilin-1 splice variants enhance the co-internalisation of Met, it’s interaction with β1-integrin, and subsequent constitutive activation of FAK/p130Cas signalling in endosomes to promote colorectal cancer metastasis.
