What is "nidogen"

n. entactin

Nidogens, formerly known as entactins, are a family of sulfated monomeric glycoproteins located in the basal lamina. Two nidogens have been identified in humans: nidogen-1 (NID1) and nidogen-2 (NID2). Nidogens have been shown to play a crucial role during organogenesis in late embryonic development, particularly in cardiac and lung development.
