ITIH1
Function
May act as a carrier of hyaluronan in serum or as a binding protein between hyaluronan and other matrix protein, including those on cell surfaces in tissues to regulate the localization, synthesis and degradation of hyaluronan which are essential to cells undergoing biological processes.
Contains a potential peptide which could stimulate a broad spectrum of phagocytotic cells.
Post-translational modifications
Heavy chains are linked to bikunin via chondroitin 4-sulfate esterified to the alpha-carboxyl of the C-terminal aspartate after propeptide cleavage.
The S-linked glycan is composed of two 6-carbon sugars, possibly Glc or Gal.
Sequence Similarities
Belongs to the ITIH family.
