A genetically linked marker locus is sought for the Booroola gene (FecB), a major gene which confers increased prolificacy in sheep. We examined 18 polymorphic proteins in sheep and found 10 to be informative in half-sib families where the Booroola gene was segregating. Recombination was observed between each of the protein loci and the Booroola gene. The loci and exclusion distance for each (calculated as the recombination fraction where the lod score was equal to -2.0) are as follows: NADH diaphorase, DIA1 (9.2 cM); arylesterase, EsA (11.9 cM); haemoglobin beta chain, HBB (17.5 cM); leucine amino peptidase, LAP (19.7 cM); malic enzyme, ME1 (14.8 cM); ovine plasminogen antigen, OPA (12.6 cM); alpha-1-protease inhibitor, PI2 (5.7 cM), erythrocyte 'X' protein, Prot-X (25.3 cM); post transferrin, PTF (2.2 cM); transferrin, TF (33.8 cM).

Eukaryotic initiation factor 5A (eIF-5A) is the only protein in nature that contains hypusine, an unusual amino acid formed post-translationally by deoxyhypusine synthase and deoxyhypusine hydroxylase. Genetic and pharmacological evidence suggests that eIF-5A is essential for cell survival and proliferation. However, the precise function and interacting partners of eIF-5A remain unclear. We have shown previously that eIF-5A can bind to RRE (Rev-response element) and U6 RNA in vitro. Using SELEX (systematic evolution of ligands by exponential enrichment), we have also shown that eIF-5A is capable of binding to RNA in a sequence-specific manner [Xu and Chen (2001) J. Biol. Chem. 276, 2555-2561]. In the present paper, we show that the identification of mRNA species that bind to eIF-5A can be achieved by affinity co-purification and PCR differential display. Using this approach with three sets of anchoring and arbitrary primers, we have found 20 RNA sequences that co-purified specifically with eIF-5A. Five of them contained AAAUGU, the putative eIF-5A-interacting element that we identified previously using the SELEX method. Direct binding of the cloned RNA to eIF-5A could be demonstrated by electrophoretic mobility-shift assay. BLAST analysis revealed that the eIF-5A-interacting RNAs encode proteins such as ribosomal L35a, plasminogen activation inhibitor mRNA-binding protein, NADH dehydrogenase subunit and ADP-ribose pyrophosphatase. Some, however, encode hypothetical proteins. All the cloned RNAs have the potential to form extensive stem-loop structures.
