Abstract:
Gata4 is an important transcription factor in heart development. Gata4 post-transcriptional protein modification regulates transcriptional activity and DNA binding, which in turn affects expression of downstream genes and transcription factors, differentiation of embryonic stem cells and cardiogenesis. This article summarizes the effect of post-transcriptional protein modification on transcriptional activity of Gata4 and the relationship between this effect and congenital heart disease. It was shown that acetylation, phosphorylation and SUMOylation upregulate transcriptional activity, DNA binding, downstream gene expression and embryonic stem cell differentiation. On the other hand, methylation and deacetylation downregulate Gata4 transcriptional activity. Post-transcriptional protein modification of Gata4 is very important in clinical research on congenital and other heart diseases.
