The suppressor of forked [su(f)] locus of Drosophila melanogaster encodes at least one cell-autonomous vital function. Mutations at su(f) can affect the expression of unlinked genes where retroviral-like transposable elements are inserted. Changes in phenotype are correlated with changes in mRNA profiles, indicating that su(f) affects the production and/or stability of mRNAs. We have cloned the su(f) gene by P-element transposon tagging. Alterations in the DNA map of eight lethal alleles were detected in a 4.3-kb region. P-element-mediated transformation using a fragment including this interval rescued all aspects of the su(f) mutant phenotype. The gene is transcribed to produce a major 2.6-kb RNA and minor RNAs of 1.3 and 2.9 kb, which are present throughout development, being most abundant in embryos, pupae, and adult females. The major predicted gene product is an 84- kD protein that is homologous to RNA14 of Saccharomyces cerevisiae, a vital gene where mutation affects mRNA stability. This suggests that phenotypic modification by su(f) occurs at the level of RNA stability.
