AB - Marbling, defined by the amount and distribution of intramuscular
fat is an economically important trait of beef cattle in Japan. Researchers
have earlier showed that the Myosin Binding Protein C, slow type (MYBPC1)
gene, known to interact with muscle protein including myosin, actin and titin
to regulate muscle contraction and to express in slow-twitch oxidative fiber
that is observed in high-marbled muscle and involved in development and maintenance
of the fiber, possesses expression differences in musculus longissimus muscle
between low-marbled Holstein and high-marbled Japanese Black steer groups. In
the present study, researchers found that a marker (DIK4787) close to the MYBPC1
was polymorphic between low-marbled Holstein and high-marbled Japanese Black
steer groups and exhibited significantly different allelic distribution between
Japanese Black sires with extremely high predicted breeding value for marbling
and with extremely low one. Further, researchers detected 3 Single Nucleotide
Polymorphisms (SNPs) in the promoter region of the MYBPC1 gene between
low-marbled Holstein and high-marbled Japanese Black steer groups. A SNP in
the upstream of the promoter of the MYBPC1, referred to as g.70014208G>A,
exhibited significantly different allelic distribution between animals with
extremely high predicted breeding value for marbling and with extremely low
one (p = 0.046). The other 2 SNPs seemed not to segregate in Japanese Black
beef cattle. The findings suggest that the g.70014208G>A SNP may be related
to changes in MYBPC1 gene expression and/or marbling. The g.70014208G>A
SNP marker may be useful for effective marker-assisted selection to increase
the levels of marbling.
