Previous GeneCards Identifiers for MGEA5 Gene
The dynamic modification of cytoplasmic and nuclear proteins by O-linked N-acetylglucosamine (O-GlcNAc) addition and removal on serine and threonine residues is catalyzed by OGT (MIM 300255), which adds O-GlcNAc, and MGEA5, a glycosidase that removes O-GlcNAc modifications (Gao et al., 2001 [PubMed 11148210]).[supplied by OMIM, Mar 2008]
GeneCards Summary for MGEA5 Gene
MGEA5 (Meningioma Expressed Antigen 5 (Hyaluronidase)) is a Protein Coding gene. Diseases associated with MGEA5 include Gm2-Gangliosidosis, Ab Variant and Diabetes Mellitus, Insulin-Dependent, 24. Among its related pathways are Insulin resistance. Gene Ontology (GO) annotations related to this gene include histone acetyltransferase activity and beta-N-acetylglucosaminidase activity.
UniProtKB/Swiss-Prot for MGEA5 Gene
Isoform 1: Cleaves GlcNAc but not GalNAc from O-glycosylated proteins. Can use p-nitrophenyl-beta-GlcNAc and 4-methylumbelliferone-GlcNAc as substrates but not p-nitrophenyl-beta-GalNAc or p-nitrophenyl-alpha-GlcNAc (in vitro) (PubMed:11148210). Does not bind acetyl-CoA and does not have histone acetyltransferase activity (PubMed:24088714).
Isoform 3: Cleaves GlcNAc but not GalNAc from O-glycosylated proteins. Can use p-nitrophenyl-beta-GlcNAc as substrate but not p-nitrophenyl-beta-GalNAc or p-nitrophenyl-alpha-GlcNAc (in vitro), but has about six times lower specific activity than isoform 1.
