abstract：:A novel gene, prom-1, was isolated in a screen for Caenorhabditis elegans mutants with increased apoptosis in the germline. prom-1 encodes an F-box protein with limited homology to the putative human tumor suppressor FBXO47. Mutations in the prom-1 locus cause a strong reduction in bivalent formation, which results in...
