Abstract:
:As part of an ongoing project aimed at the characterization of the MHC system in bony fishes, we have attempted to identify the class III region in the zebrafish (a teleost), a region that in higher vertebrates contains genes coding for complement proteins C2, Bf and C4. We obtained several genomic PAC clones by hybridization with a zebrafish Bf probe, previously identified in our laboratory, and searched these for the presence of other class III genes. We were able to obtain a second Bf-like gene, however, we were unable to detect any C2- or C4-like genes. By using highly degenerated primers, we extended our search to a hepatopancreas cDNA library and amplified from it clones corresponding to three different C3-like genes, and also the Bf genes, but not any C2- or C4-like genes. The zebrafish therefore contains two Bf and three C3 loci but apparently no C2 and C4 loci. Independent duplications of the Bf and C3 genes in bony fishes suggest that complement plays a prominent part in the immune response of this class of vertebrates.
