NOD1 is a cytosolic immune receptor well known for recognizing intracellular bacteria and inducing innate immune responses. Upon ligand binding, it usually forms a complex with the serine/threonine kinase RIPK2 to activate the transcription factor NF-κB. Next to its role in pathogen recognition, NOD1 has been associated with cancer progression. In this regard, Hezinger et al. investigated a non-canonical role of NOD1 in cell migration. They discovered that NOD1 is crucial for the migration and chemotaxis of HeLa cells and identified HAX-1 as a novel interaction partner.
Keywords: Nod-like receptors; cell migration; innate immunity.
