SIAE Proteins and Enzymes

Sialic acids are acidic 9-carbon sugars typically found at the nonreducing end of sugar chains. They are frequently modified by 9-O-acetylation, and this modification is removed by sialic acid acetylesterases. SIAE appears to encode both lysosomal and cytosolic sialic acid acetylesterase isoforms (LSE and CSE, respectively) (Takematsu et al., 1999 [PubMed 10464298]).[supplied by OMIM]
