Abstract :In the present study, an 84-bp insertion/deletion polymorphism of the sterol regulatory element-binding protein 1 insert ignore into journalissuearticles values(SREBP1); gene was investigated. The analysis included 6 Polish cattle herds consisting of beef insert ignore into journalissuearticles values(Limousin, Angus, Charolais);, dairy insert ignore into journalissuearticles values(Holstein-Friesian, Jersey); and dual-purpose insert ignore into journalissuearticles values(Montbeliard); breeds. The polymorphism was found only in Limousin and Montbeliard animals, in which both the short insert ignore into journalissuearticles values(S);- and long insert ignore into journalissuearticles values(L);-type alleles occurred. The genotype distribution in Montbeliard cattle was as follows: 0.038, 0.406, and 0.556 for SS, LS, and LL, respectively. To the author`s knowledge, this study was the first to investigate the above-mentioned polymorphic site in the Montbeliard and Jersey cattle populations. As far as SREBP1 function is concerned, the examined locus seems to be a very interesting object for further investigations, such as association studies for fatty acid content and composition in cattle milk.
