Clinical mutations in the L1 neural cell adhesion molecule affect cell-surface expression.
Mutations in the L1 neural cell adhesion molecule, a transmembrane glycoprotein, cause a spectrum of congenital neurological syndromes, ranging from hydrocephalus to mental retardation. Many of these mutations are single amino acid changes that are distributed throughout the various domains of the protein. Defective herpes simplex virus vectors were used to express L1 protein with the clinical ...
متن کاملImpact of L1 Cell Adhesion Molecule on Macrophage Activation
INTRODUCTION Nowadays, per research study, around 5.6 million people around the United States suffer from paralysis [1]. There are many reasons that contribute to paralysis: stroke, spinal cord injuries, multiple sclerosis and so on. Patients who suffer from paralysis lose partial or fully sensory function and motor intention. Although paralysis is not life-threatening for most of the patients,...
متن کاملCytoplasmic domain mutations of the L1 cell adhesion molecule reduce L1-ankyrin interactions.
The neural adhesion molecule L1 mediates the axon outgrowth, adhesion, and fasciculation that are necessary for proper development of synaptic connections. L1 gene mutations are present in humans with the X-linked mental retardation syndrome CRASH (corpus callosum hypoplasia, retardation, aphasia, spastic paraplegia, hydrocephalus). Three missense mutations associated with CRASH syndrome reside...
متن کاملEffects of Ethanol and NAP on Cerebellar Expression of the Neural Cell Adhesion Molecule L1
The neural cell adhesion molecule L1 is critical for brain development and plays a role in learning and memory in the adult. Ethanol inhibits L1-mediated cell adhesion and neurite outgrowth in cerebellar granule neurons (CGNs), and these actions might underlie the cerebellar dysmorphology of fetal alcohol spectrum disorders. The peptide NAP potently blocks ethanol inhibition of L1 adhesion and ...
متن کاملCell adhesion molecule L1 in folded (horseshoe) and extended conformations.
We have investigated the structure of the cell adhesion molecule L1 by electron microscopy. We were particularly interested in the conformation of the four N-terminal immunoglobulin domains, because x-ray diffraction showed that these domains are bent into a horseshoe shape in the related molecules hemolin and axonin-1. Surprisingly, rotary-shadowed specimens showed the molecules to be elongate...
