anomalous protein migration on PAGE ?

Does anyone have any experience with proteins that migrate significantly slower
by SDS-PAGE than their DNA sequence predicts?  I have a 22.3 Kd ORF that yields
a 35 Kd polypeptide on gels.  I would like to know if someone has similar
experience or some possible explanation(s).
