Positive Selection in Zinc Finger Protein Reveals Genetic Signatures of Adaptive Evolution in Undifferentiated Stem Cells during Evolution in Mammals

Figure 4

High sequence similarity and conserved ZFP42 gene expression patterns across several mammalian species imply that the protein has an essential and evolutionarily conserved function. It is also a useful model for researching stem cell biology and early development due to the gene’s conservation across species.
