Heterogeneity of Tau proteins during mouse brain development and differentiation of cultured neurons

J C Larcher et al. Dev Biol. 1992 Nov.

Abstract

Tau microtubule-associated proteins constitute a group of developmentally regulated neuronal proteins. Using the high-resolution two-dimensional polyacrylamide gel electrophoresis system, we have resolved more than 60 distinct Tau isoforms in the adult mouse brain. Tau protein heterogeneity increases drastically during the second week of brain development. In neuronal primary cell cultures, some of these developmental changes can be observed. The increase of Tau heterogeneity in culture is more limited and reaches a plateau after a period corresponding to the second week of development. Most, if not all, of the vast Tau heterogeneity can be attributed to intensive post-translational phosphorylation, which may affect the structure of the proteins.
