Also known as: 49Fk; CG4654; dDp; dDP; dDP1; DDP1; DmDP; Dmel\CG4654; dp; DP; Dp1; DP1; l(2)49Fk; l(2)vr10; TFPD2; vr10
Summary: Enables DNA binding activity and DNA-binding transcription factor binding activity. Contributes to DNA-binding transcription factor activity, RNA polymerase II-specific and sequence-specific DNA binding activity. Involved in several processes, including dorsal/ventral axis specification, ovarian follicular epithelium; intrinsic apoptotic signaling pathway in response to DNA damage; and positive regulation of nurse cell apoptotic process. Located in nucleus. Part of Myb complex and Rb-E2F complex. Is expressed in several structures, including embryonic/larval midgut primordium; epithelium; ganglia; imaginal disc; and male germline cell. Human ortholog(s) of this gene implicated in mismatch repair cancer syndrome. Orthologous to human TFDP3 (transcription factor Dp family member 3); TFDP1 (transcription factor Dp-1); and TFDP2 (transcription factor Dp-2). [provided by Alliance of Genome Resources, Jul 2025]

What's a GeneRIF?

These findings identify a key function of E2F/Dp in skeletal muscle required for animal viability, and illustrate how the cell cycle regulator is repurposed in post-mitotic cells.
Title: E2F function in muscle growth is necessary and sufficient for viability in Drosophila.
results suggest that E2F/DP complexes are essential for all genomic targeting of RBF1
Title: RBF binding to both canonical E2F targets and noncanonical targets depends on functional dE2F/dDP complexes.
Dampened transcriptional activation by E2F1-DP and Myb-MuvB is important to repress mitosis and coordinate the endocycle transcription
Title: Dampened activity of E2F1-DP and Myb-MuvB transcription factors in Drosophila endocycling cells.
dDP is required for normal cell proliferation, for optimal DNA synthesis, and for efficient G2/M progression.
Title: dDP is needed for normal cell proliferation.
