NCBI Protein Information
Transcription factor DP
NCBI Summary
Encodes a homolog of the animal DP protein. DP, in animals, forms a heterodimer with E2F and plays a central role in G1/S transition in the cell division cycle. DPB has been shown to interact with non phosphorylated E2Fc; when E2Fc is phosphorylated, the formation of the E2Fc/DPB heterodimer is lost.

UniProt Comments
Involved in the regulation of the G1/S transition. Increases the DNA binding activity of E2F proteins after heterodimerization. The complex DPB/E2FC restricts cell division and lateral root initiation and may function as a negative regulator of E2F-regulated genes. The interaction with SKP2A is controlled by auxin.
