Our previous studies indicated that regulation of N-cadherin expression differs spatially and temporally among tissues of the eye, possibly reflecting the distinct roles it has in the development and maintenance of eye tissues. To understand this regulation of N-cadherin expression and its function in different tissues during embryonic development, we investigated the post-translational modifications of N-cadherin and its association with the cytoskeleton. We show that N-cadherin is a sulfated and phosphorylated protein. The phosphorylation of N-cadherin occurs in an age- and tissue-specific pattern during development in the neural retina, brain, lens and heart. The extent of sulfation of N-cadherin is also age-dependent, and both sulfated and unsulfated pools of N-cadherin exist in the same tissue as indicated by two-dimensional electrophoresis. The degree of association of N-cadherin with the cytoskeleton differs from one tissue to another, as well as within a single tissue at different stages of development. A positive correlation was found between the extent, developmental timing, and tissue specificity of N-cadherin phosphorylation and the degree of N-cadherin association with the cytoskeleton. Our results suggest the existence of a microheterogeneous population of N-cadherin molecules, within which posttranslational modification of N-cadherin may affect its association with the cytoskeleton and its expression and function during development.
