EXT2_DROME - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: EXT2_DROME
• UniProt AC: Q9Y169
• Protein Name: Exostosin-2
• Gene Name: Ext2
• Organism: Drosophila melanogaster (Fruit fly).
• Sequence Length: 717
• Subcellular Localization: Endoplasmic reticulum membrane; Single-pass type II membrane protein. Golgi apparatus membrane ; Single-pass type II membrane protein . Localization to the Golgi may be regulated by sau (PubMed:23720043).
• Protein Description: Glycosyltransferase required for the biosynthesis of heparan-sulfate and responsible for the alternating addition of beta-1-4-linked glucuronic acid (GlcA) and alpha-1-4-linked N-acetylglucosamine (GlcNAc) units to nascent heparan sulfate chains. Plays a central role in diffusion of morphogens hedgehog (hh), wingless (wg) and Decapentaplegic (dpp) via its role in heparan sulfate proteoglycans (HSPGs) biosynthesis, HSPGs being required for movement of Hh, Dpp and wg morphogens..
