Significance of PTMs | The protein contains two (human) or three (murine) N-glycosilation sites, yielding a glycoprotein with a molecular mass of 20 kD that is reduced to 15 kD after deglycosylation .Removal of the N-linked glycosidic side chains does not abrogate the bioactivity of the protein.A sequence encoding a hydrophobic stretch of peptide precedes the sequence coding for the mature protein. This putative signal peptide is cleaved from the protein before secretion. |
