Summary: A structural constituent of postsynaptic intermediate filament cytoskeleton. Involved in postsynaptic modulation of chemical synaptic transmission. Acts upstream of or within cellular response to leukemia inhibitory factor and neurofilament cytoskeleton organization. Located in neurofilament. Is active in Schaffer collateral - CA1 synapse and postsynapse. Is expressed in several structures, including gut; nervous system; neural ectoderm; and sensory organ. Orthologous to human INA (internexin neuronal intermediate filament protein alpha). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Neurofilament light chain (NFL) and neuronal intermediate filament protein alpha-internexin accumulate in axon swellings in the spinal white matter in superoxide dismutase (SOD)-1 mouse.
Title: Degeneration of axons in spinal white matter in G93A mSOD1 mouse characterized by NFL and α-internexin immunoreactivity.
RE1 silencing transcription factor (REST) plays a contributory role in the neuron-specific expression of the alpha-internexin, NF-H and NF-M genes
Title: RE1 silencing transcription factor is involved in regulating neuron-specific expression of alpha-internexin and neurofilament genes.
abnormal accumulation of neuronal IFs in the swelling axons and abnormal translocation of alpha-internexin in the nuclei of the spinal motor neurons from dystonia musculorum mice may not directly cause cell death of the spinal motor neurons
Title: Abnormal cellular translocation of alpha-internexin in spinal motor neurons of Dystonia musculorum mice.
Therefore, the cre transgene driven by mouse alpha-internexin promoter, described here, provides a useful animal model to specifically manipulate genes in the developing nervous system.
Title: Neural expression of alpha-internexin promoter in vitro and in vivo.
Alpha-internexin coassembles with all 3 neurofilament proteins into a single network of filaments. All of them are functionally interdependent. It is a fourth subunit of neurofilaments in the adult CNS.
Title: Alpha-internexin is structurally and functionally associated with the neurofilament triplet proteins in the mature CNS.

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.
