Lectican

Lecticans, also known as hyalectans, are a family of proteoglycans (a type protein that is attached to chains of negatively charged polysaccharides) that are components of the extracellular matrix. There are four members of the lectican family: aggrecan, brevican, neurocan, and versican. Lecticans interact with hyaluronic acid and tenascin-R to form a ternary complex.
