Molecular characterization and expression patterns of the actinin-associated LIM protein (ALP) subfamily genes in porcine skeletal muscle

The actinin-associated LIM protein (ALP) subfamily has important functions in cell signal transduction, cell proliferation, and integration of cytoskeletal architecture. To detect their functions in pig skeletal muscle, we cloned and characterized the pig ALP subfamily genes, drew their genomic structure maps, and detected their tissue expression patterns. We identified a new spliced variant of PDLIM3 in pig skeletal muscle and named it as PDLIM3-4, which was only expressed in the heart and skeletal muscle. Our results showed that PDLIM3-4 was expressed in adult pig skeletal muscle with the highest expression level, and both PDLIM3-4 isoform and PDLIM4 had different expression profiles during the prenatal and postnatal stages of skeletal muscle development among the three pig breeds. These studies provide useful information for further research on the functions of pig ALP subfamily genes in skeletal muscle development.
