FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a component of the gamma-tubulin ring complex, which is required for microtubule nucleation. In mammalian cells, the protein localizes to centrosomes in association with gamma-tubulin. Crystal structure analysis revealed a structure composed of five helical bundles arranged around conserved hydrophobic cores. An exposed surface area located in the C-terminal domain is essential and sufficient for direct binding to gamma-tubulin. Mutations in this gene that alter microtubule organization are associated with microcephaly and chorioretinopathy. Alternative splicing results in multiple transcript variants.

| Nature of Mutation |
 DNA sequencing using the SOLiD technique identified a C to T transition at position 912 of the Tubgcp4 transcript in exon 8 of 18 total exons. Multiple transcripts of the Tubgcp4 gene are displayed on Ensembl and Vega. The mutated nucleotide causes an arginine to cysteine substitution at amino acid 242 of the encoded protein. This residue occurs at an intron/exon boundary and may also affect splicing. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
|
| Protein Function and Prediction |
The Tubgcp4 gene encodes a 667 amino acid component of the gamma-tubulin complex, which is necessary for microtubule nucleation at the centrosome (Uniprot Q9D4F8).
The R242C change is predicted to be probably damaging by the PolyPhen program (see report). |
