Molecular characterization, polymorphism and association of porcine MYST2 gene.


PMID 22327654

Abstract

MYST histone acetyltransferase 2 (MYST2) is an important reproduction related gene. In this study, we cloned the full-length cDNA sequence of porcine MYST2 gene through the rapid amplification of cDNA ends method. The porcine MYST2 gene encodes a protein of 611 amino acids which shares high homology with the MYST2 of six species: cattle (99%), rabbit (99%), human (99%), rat (99%), mouse (99%) and chicken (98%).The open reading frame of this gene is structured in 15 exons and 14 introns as revealed by computer-assisted analysis. The phylogenetic analysis revealed that the porcine MYST2 gene has a closer genetic distance with the MYST2 gene of cattle. PCR-RFLP was established to detect the GU373686:c.2872G > A substitution of porcine MYST2 gene mRNA and association of this mutation with litter size traits was assessed in Large White (n = 200) and Landrace (n = 200) pig populations. Results demonstrated that this polymorphic locus was significantly associated with the litter size of all parities in Large White sows and Landrace sows. These data serve as a foundation for further insight into this porcine gene.
