title: Molecular characterization of the encoding regions and tissue expression analyses for three novel porcine genes--HNRPA1, YIPF5 and UB2D2.
abstract: The complete encoding regions of three porcine genes--heterogeneous nuclear ribonucleoprotein A1 (HNRPA1), YIP1 family member 5 (YIPF5) and ubiquitin-conjugating enzyme E2 D2 (UB2D2) were amplified using the reverse transcriptase polymerase chain reaction (RT-PCR) based on the conserved encoding region information of the mouse or other mammals and the referenced highly homologous pig ESTs of these conserved encoding regions. These three novel porcine genes were assigned to GeneID: 768103, 768112, and 780418. The phylogenetic tree analysis revealed that the swine HNRPA1 has closer genetic relationships with the HNRPA1 of mouse and rhesus monkey, but the swine YIPF5 has a closer genetic relationship with the YIPF5 of cattle and the swine UB2D2 shows an evolutional model different with the UB2D2 of other five species. The tissue expression analysis indicated that the swine HNRPA1 gene was moderately expressed in fat, spleen and kidney, weakly expressed in muscle and lung, and hardly expressed in small intestine, large intestine and liver. The swine YIPF5 gene was moderately expressed in fat and spleen, and hardly expressed in small intestine, large intestine, liver, lung, muscle and kidney. The swine UB2D2 gene was weakly expressed in lung, and hardly expressed in small intestine, large intestine, liver, muscle, fat, spleen and kidney. Our experiment established the primary foundation for further research on these three swine genes.
