Motility of the nerve growth cone is highly dependent on its dynamic interactions with the microenvironment mediated by cell adhesion molecules (CAMs). These adhesive interactions can be spatially regulated by changing the density and avidity of CAMs on the growth cone. Previous studies have shown that L1, a member of the immunoglobulin superfamily of CAMs,(More)
Axonal growth cones migrate along the correct paths during development, not only directed by guidance cues but also contacted by local environment via cell adhesion molecules (CAMs). Asymmetric Ca2+ elevations in the growth cone cytosol induce both attractive and repulsive turning in response to the guidance cues (Zheng, J.Q. 2000. Nature. 403:89-93;(More)
The cell adhesion molecule L1 (L1-CAM) plays critical roles in neurite growth. Its cytoplasmic domain (L1CD) binds to ankyrins that associate with the spectrin-actin network. This paper demonstrates that L1-CAM interactions with ankyrinB (but not with ankyrinG) are involved in the initial formation of neurites. In the membranous protrusions surrounding the(More)
Polyedrisches Protein hat die Fähigkeit, das Wachstum von Sarkom-180 zu hemmen. Hitze-denaturierte DNS ist fähig, sich mit diesem Protein zu kombinieren, was von einem Aufbrechen des Proteins begleitet wird. Partiell mit Trypsin hydrolysiertes Protein kann sich auch an einstrangige Nucleinsäure binden, eine Bindung, welche seine Neigung zum Aufbrechen(More)
