Spatial and temporal effects in protein post-translational modification distributions in the developing mouse brain.

Protein post-translational modification (PTM) is a powerful way to modify the behavior of cellular proteins and thereby cellular behavior. Multiple recent studies of evolutionary trends have shown that certain pairs of protein post-translational modifications tend to occur closer to each other than expected at random. This type of observation may form the basis of a proposed "PTM code", whereby protein function is controlled by complex patterns of multiple PTMs.
