Protein

Tubulin gamma-1 chain

Gene

TUBG1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Tubulin is the major constituent of microtubules. The gamma chain is found at microtubule organizing centers (MTOC) such as the spindle poles or the centrosome. Pericentriolar matrix component that regulates alpha/beta chain minus-end nucleation, centrosome duplication and spindle formation.

Involvement in diseasei

Cortical dysplasia, complex, with other brain malformations 41 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA disorder of aberrant neuronal migration and disturbed axonal guidance. Clinical features include early-onset seizures, microcephaly, spastic tetraplegia, and various malformations of cortical development, such as agyria, posterior or frontal pachygyria, thick cortex, and subcortical band heterotopia and thin corpus callosum in some patients.

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
