Gene name

SIAE

Description

sialic acid acetylesterase

Protein class

Enzymes, Mapped to UniProt SWISS-PROT, Potential transmembrane proteins, Potentially secreted proteins

Protein evidence

High

Entrez gene summary

This gene encodes an enzyme which removes 9-O-acetylation modifications from sialic acids. Mutations in this gene are associated with susceptibility to autoimmune disease 6. Multiple transcript variants encoding different isoforms, found either in the cytosol or in the lysosome, have been found for this gene.[provided by RefSeq, Feb 2011]
