Abstract:

The objective of this study was to analyze the reasons of different functions of NF-κB1/2 and to identify the evolutionary status of its domains.The sequence information of NF-κB1/2 was analyzed by following bioinformatic methods,including multiple sequence alignment phylogenetic tree construction and selective pressure prediction.The results showed that there was no intersection among vertebrate NF-κB1/2 during evolution,and RHD and IPT were highly conserved;ANK had diverged among both orthologous and paralogous structures;DD showed a high conservation with orthologous structures but a large difference with paralogous structures.Our results suggested that NF-κB1/2 were highly conservative among vertebrates,and the sequence variation of ANK might be an important factor causing the different functions of NF-κB1/2 in vertebrate,and DD might be one of the reasons for the divergence of NF-κB1/2 genes.
