AbstractThe class V POU family genes, including pou5f1 and pou2, encode transcription factors critical for the maintenance of pluripotency in embryonic stem cells (ESC) and germ line cells in vertebrates. In the present study, the full-length cDNA of a pou2 ortholog in A. sinensis, Aspou2, was cloned and sequenced. This cDNA sequence is 2,853 base pairs in length and encodes a peptide of 431 amino acid residues. A comparison of the deduced amino acid sequence of Aspou2 with that of other vertebrate species showed that they were highly conserved in the POU domain, which shared 88 and 90% identity with that of zebrafish and medaka, respectively, and was 69, 67 and 67% identical to frog, mouse and human, respectively. RT-PCR analysis revealed that Aspou2 was detected in all tissues examined except for the liver, and high mRNA levels of Aspou2 were found in the muscle, pituitary and brain. During the embryogenesis and early larval development, the expression level of Aspou2 mRNAs decreased gradually apart from 1-day larvae that were not observed. Furthermore, Aspou2 seemed to raise with the development of gonads of immature Chinese sturgeons. These results suggested the possible involvement of Aspou2 in the nonpluripotent cells, pluripotent cells, embryogenesis, and gonad development.; The class V POU family genes, including pou5f1 and pou2, encode transcription factors critical for the maintenance of pluripotency in embryonic stem cells (ESC) and germ line cells in vertebrates.
