Since, there is no change in the pI after post translational modification, it means the post translational modification cannot be phosphorylation, ADP ribosylation or ubiquitination as these three modifications will change the ionization state of protein and hence change the pI so on IEF their location will be different. Therefore the given protein has glycosylation modification. Also serine cannot undergo ubiquitination; ubiquitination occurs on lysine residue.
