Summary: This gene encodes a member of the tubulin superfamily. The encoded protein localizes to the centrosome where it binds to microtubules as part of a complex referred to as the gamma-tubulin ring complex. The protein mediates microtubule nucleation and is required for microtubule formation and progression of the cell cycle. A pseudogene of this gene is found on chromosome 7.

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.
