| PubMed Abstract |
Proteins produced by the homeotic genes of the Hox family assign different identifies to cells on the anterior/posterior axis.
Relatively little is known about the signalling pathways that modulate their activities or the factors with which they interact
to assign specific segmental identifies. To identify genes that might encode such functions, we performed a screen for second
site mutations that reduce the viability of animals carrying hypomorphic mutant alleles of the Drosophila homeotic locus,
Deformed. Genes mapping to six complementation groups on the third chromosome were isolated as modifiers of Deformed function.
Products of two of these genes, sallimus and moira, have been previously proposed as homeotic activators since they suppress
the dominant adult phenotype of Polycomb mutants. Mutations in hedgehog, which encodes secreted signalling proteins, were
also isolated as Deformed loss-of-function enhancers. Hedgehog mutant alleles also suppress the Polycomb phenotype. Mutations
were also isolated in a few genes that interact with Deformed but not with Polycomb, indicating that the screen identified
genes that are not general homeotic activators. Two of these genes, cap 'n' collar and defaced, have defects in embryonic
head development that are similar to defects seen in loss of function Deformed mutants.
