Summary: Predicted to enable GTP binding activity; identical protein binding activity; and microtubule nucleator activity. Involved in meiotic spindle organization. Located in several cellular components, including condensed nuclear chromosome; microtubule cytoskeleton; and non-motile cilium. Is expressed in several structures, including central nervous system; eye; head mesenchyme; heart; and respiratory system. Used to study complex cortical dysplasia with other brain malformations 4. Human ortholog(s) of this gene implicated in complex cortical dysplasia with other brain malformations 4; inclusion body myositis; and muscular disease. Orthologous to human TUBG1 (tubulin gamma 1).

Study investigated the consequences of four human malformations of cortical development-related TUBG1 variants by using in utero electroporation and a knock-in Tubg1Y92C/+ mouse model and show that pathogenic TUBG1 variants affect neuronal positioning by disrupting neuronal migration and affecting microtubule dynamics rather than centrosomal positioning or nucleation ability.

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.
