Keratocan

Keratocan (KTN) also known as keratan sulfate proteoglycan keratocan is a is_associated_with::protein that in humans is encoded by the KERA is_associated_with::gene.

is_associated_with::Keratan sulfate is_associated_with::proteoglycans (KSPGs) are members of the small leucine-rich proteoglycan (SLRP) family. KSPGs, particularly keratocan, is_associated_with::lumican and is_associated_with::mimecan, are important to the transparency of the is_associated_with::cornea.
