Discovery of single nucleotide polymorphisms in FABP3 and leptin gene in pig (Brief Report)

Abstract. Knowledge about structural variations in genes and proteins relevant for fat traits is very important information to improve selection of breeding lines and preserve genetic variability in pig industry. The classical proteomics is a useful tool to separate and measure differentially expressed proteins in fat tissue of phenotypic different individual pigs. Single nucleotide polymorphisms (SNP) in the swine adipocyte fatty-acid binding protein 3 (FABP3) and leptin gene (LEP) were related to adipocyte accumulation and associated with meat quality in pigs (NECHTELBERGER et al. 2001, KULIG et al. 2001, KMIEC et al. 2003).
