Skeletal muscle and kidney-enriched inositol phosphatase (SKIP) was identified as a 5'-inositol phosphatase that hydrolyzes phosphatidylinositol (3,4,5)-triphosphate (PI(3,4,5)P3) to PI(3,4)P2 and negatively regulates insulin-induced phosphatidylinositol 3-kinase signaling in skeletal muscle. In this study, two new single nucleotide polymorphisms (SNPs) in porcine SKIP introns 1 and 6 were detected. The C1092T locus in intron 1 showed significant associations with some meat traits, whereas the A17G locus in intron 6 showed significant associations with some carcass traits. Expression analysis showed that porcine SKIP is upregulated at d 65 of gestation and Meishan fetuses have higher and prolonged expression of SKIP compared to Large White at d 100 of gestation. Ectopic expression of porcine SKIP decreased insulin-induced cell proliferation and promoted serum starvation-induced cell cycle arrest in G0/G1 phase in C2C12. Our results suggest that SKIP plays a negative regulatory role in skeletal muscle development partly by preventing cell proliferation.
