Identification and Characterization of the OCT4 Upstream Regulatory Region in Sus scrofa

Table 1

Alignment of the nucleotide sequences from porcine OCT4 promoter regions with those of six mammalian species (%).

Regions	Pig-mouse	Pig-vole	Pig-rabbit	Pig-cow	Pig-goat	Pig-human
CR1	76.8	76.0	83.5	66.7	94.5	89.1
CR2	83.3	78.7	77.4	90.1	88.1	94.2
CR3	93.5	88.4	94.9	98.5	97.9	96.4
CR4	80.8	79.7	87.0	91.5	91.6	89.2
5 UR	54.8	54.1	63.8	62.0	70.7	60.8

The regions with the highest homology are bolded. CR1: conserved region 1; CR2: conserved region 2; CR3: conserved region 3; CR4: conserved region 4; 5 UR: 5 upstream region. Gap region in the cow Oct4 URS -2908/-2809 sequence.
