Summary
Predicted to enable ATP hydrolysis activity; microtubule binding activity; and microtubule motor activity. Involved in regulation of postsynaptic membrane neurotransmitter receptor levels and retrograde dendritic transport. Acts upstream of or within corpus callosum development. Is active in glutamatergic synapse and postsynaptic endosome. Is expressed in central nervous system; dorsal root ganglion; and neural retina. Orthologous to human KIF21B (kinesin family member 21B).

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.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) contains an alternate exon in the 3' end compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
