Abstract

Genes coding for sarcomeric proteins may play a key role in muscle mass accretion and meat production. Screening a skeletal muscle cDNA library we isolated two partial sequences coding for the sarcomeric myopalladin and titin genes. In the present work we identified three SNPs in the 3' untranslated region, two at the myopalladin locus and one at the titin locus. Myopalladin was mapped on porcine chromosome (SSC) 14 using a somatic cell hybrid panel, a radiation hybrid panel and by linkage mapping. The linkage mapping of titin confirmed the position on SSC15. Then we analysed the allelic distribution of the alleles at both loci in six different porcine breeds. The analysis of the allele frequencies for these two loci in extremely divergent groups of pigs selected according to lean cuts (LC) and average daily gain (ADG) approached the significance level for myopalladin and LC trait. Further studies are needed to test the presence of a putative effect of myopalladin on lean meat content.
