Glycosylation in the nervous system is thought to play a particularly important and dynamic role in both vertebrates and invertebrates. Mucin-type O-glycosylation is initiated by a large family of UDP- GalNAc:polypeptideα-N-acetylgalactosaminyltransferases (ppGalNAc-Ts, EC 2.4.1.41) which contains 20 members. ppGalNAc-T13 is one of the essential isoform, and has been found highly and restrictively expressed in the brain and neurons [1]. In this study, we found that the mRNA and protein expression of ppGalNAc-T13 was dramatically increasing during the all-trans retinoic acid (ATRA) induced neural differentiation of embryonic carcinoma P19 cells, mouse brain development and primary neuronal cultures. ppGalNAc-T13 was localized in axons of the neurons derived from P19 cells and the O-glycosylation level was simultaneously increased during the ATRA induced neural differentiation. Furthermore, up-regulation of ppGalNAc-T13 induced the formation of lamellipodia and a higher O-glycosylation level. These results imply that the high expression of ppGalNAc-T13 in neurons may play a regulatory role in the neural differentiation. Study to explore the roles of ppGalNAc-T13 in regulating neural differentiation is under way.
