What's a GeneRIF?

Recombinant rat alpha-internexin coassembles with all three neurofilament proteins into a single network of filaments in quadruple-transfected SW13vim(-) mouse cells.
Title: Alpha-internexin is structurally and functionally associated with the neurofilament triplet proteins in the mature CNS.
Alpha-internexin immunoreactive neurites were localized to plaques densely packed with beta-amyloid fibrils in preclinical AD cases, indicating that certain plaques may cause structural injury or impediment of local axonal transport.
Title: alpha-Internexin immunoreactivity reflects variable neuronal vulnerability in Alzheimer's disease and supports the role of the beta-amyloid plaques in inducing neuronal injury.
alpha-internexin plays an important role in neurite outgrowth and regulates the expression of other neurofilaments during neuronal development
Title: Overexpression of neuronal intermediate filament protein alpha-internexin in PC12 cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
