We isolated and characterized the two orthologs of sox1 from Paralichthys olivaceus.
We analyzed the Posox1a and Posox1b promoter regions for potential TF binding sites.
The gene expression profiles of Posox1a and Posox1b were analyzed by qRT-PCR.
Posox1a and Posox1b were abundantly expressed at neurula stage and in adult brain.
Posox1a and Posox1b may have a conserved function between teleosts and mammals.
