Recombinant Human CHIT1 protein (NP_001243054.2) is produced in Glycoengineered Pichia pastoris. This expression system is used for the production of glycoproteins and antibodies with human post-translational modifications.
Chitotriosidase is secreted by activated human macrophages and is markedly elevated in plasma of Gaucher disease patients. The expression of chitotriosidase occurs only at a late stage of differentiation of monocytes to activated macrophages in culture. Human macrophages can synthesize a functional chitotriosidase, a highly conserved enzyme with a strongly regulated expression. This enzyme may play a role in the degradation of chitin-containing pathogens. Several alternatively spliced transcript variants have been described for this gene.
