This page provides comprehensive information about this protein. See the content below for detailed information.
YKL-40 (also known as CHI3L1) is a secreted chitinase-like protein that lacks enzymatic activity. It serves as a biomarker for neuroinflammation and is implicated in the pathogenesis of various neurodegenerative diseases.
YKL-40 has a chitinase-like fold:
Despite structural similarity to chitinases, YKL-40 does not hydrolyze chitin.
YKL-40 has diverse biological functions:
YKL-40 is elevated in AD:
