Phosphorylation of L1-type cell-adhesion molecules--ankyrins away!
Neural cell-adhesion molecules (CAMs) are powerful initiators of neurite outgrowth during neural differentiation. In addition, their interactions with cytoskeletal components are often conserved and highly regulated. How these two aspects of neural CAM function relate to each other is not well understood. However, a recent publication from the Felsenfeld laboratory ( http://www.mssm.edu/labs/felsenfeld) fills a gap in our knowledge of how the interaction of L1-type CAMs with the membrane skeleton adaptor protein ankyrin is severed by phosphorylation and suggests a feedback mechanism whereby the neurite-stimulating activity of L1-CAM is inversely connected to its cytoskeleton binding.
