Gene or accession: CG5257 Gene annotation error Genes CG5257 and CG5253 were merged. Comments: CG5257 encodes a protein with a ribosomal S1 domain homologous to a prokaryotic family of proteins including B. pertussis Tex and several hypothetical conserved proteins. CG5253, directly upstream from CG5257 encodes a protein homologous to the this same bacterial family, but lacking an S1 domain. CG5253 and CG5257 by homology encode contiguous domains of the same protein, probably separated by a large intron.
