Aspm assembly factor for spindle microtubules [Rattus norvegicus (Norway rat)] - Gene

Summary

Official Symbol: Aspmprovided by RGD
Official Full Name: assembly factor for spindle microtubulesprovided by RGD
Primary source: RGD:1307111
See related: Ensembl:ENSRNOG00000012318 AllianceGenome:RGD:1307111
Gene type: protein coding
RefSeq status: VALIDATED
Organism: Rattus norvegicus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Also known as: Calmbp1
Summary: Predicted to enable calmodulin binding activity. Predicted to be involved in regulation of meiotic cell cycle; spindle localization; and spindle organization. Predicted to act upstream of or within several processes, including maintenance of centrosome location; nervous system development; and neuronal stem cell population maintenance. Located in apical plasma membrane; microtubule cytoskeleton; and midbody. Human ortholog(s) of this gene implicated in primary autosomal recessive microcephaly and primary autosomal recessive microcephaly 5. Orthologous to human ASPM (assembly factor for spindle microtubules). [provided by Alliance of Genome Resources, Jul 2025]
Expression: Biased expression in Thymus (RPKM 212.9), Spleen (RPKM 103.5) and 9 other tissues See more

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.
