A gene responsible for vegetative incompatibility in the fungus Podospora anserina encodes a protein with a GTP-binding motif and G beta homologous domain
1995
The het-e-1 gene of the fungus Podospora anserina is responsible for vegetative incompatibility through specific interactions with different alleles of the unlinked gene, het-c. Coexpression of two incompatible genes triggers a cell death reaction that prevents heterokaryon formation. The het-e-1 allele has been cloned to get information on the function of the locus. It encodes a putative 1356-amino-acid polypeptide that displays two sequence motifs that have not yet been reported to be present on a single polypeptide. They are a GTP-binding domain and a repeated region that shares similarity with that of the beta-transducin. Contrary to other members of the beta-transducin family, sequence conservation between the repeated units is very strong and the number of repeats is different in wild-type het-e alleles.
