| Annotation description: | Authors do not address the specific role of alpha-internexin but of neurofilaments, which are heteropolimers made up of NFL, NFM, NFH and alpha-internexin. They investigate the role of neurofilaments by creating a triple knockout mouse by knocking out alpha-internexin, NFH and NFL and address the role of these proteins in synaptic transmission. Tetanic stimulation of Schaffer-collateral pathway in slices induced LTP of fEPSPs in control but not knockout conditions, which suggest a role of these protein in synaptic transmission. Although this is not a direct confirmation of the function of alpha-internexin, the function of this protein is redundant with the function of neurofilaments. |
