Isolation, sequence identification, and tissue expression profile of 3 novel porcine genes: NCF2, BCKDHB and BCKDHA

The complete coding sequences of porcine genes NCF2, BCKDHB and BCKDHA were amplified by using reverse transcriptase polymerase chain reaction (RT-PCR), basing on the conserved coding sequence information of humans or other mammals. These 3 novel porcine genes were then assigned GeneIDs: 100142665, 100142669 and 100142666. The phylogenetic tree analysis revealed that the porcine NCF2, BCKDHB and BCKDHA all are most closely related to the bovine NCF2, BCKDHB and BCKDHA. Tissue expression profile analysis revealed that porcine NCF2, BCKDHB and BCKDHA genes were differentially expressed in tissues, including skeletal muscle, the heart, liver, fat, kidney, lung, small and large intestine.
