Jan 29, 2024 · Mechanistically, through its HLH domain, Id2 binds and disrupts the assembly of the Tcf3-Tal1 transcriptional regulatory complex, and thus modulates chromatin accessibility at the Slamf6...

A modified HEB HLH domain has been shown to interfere with and inhibit Id2 in human neuroblastoma cells. This has led to the activation of the cell-cycle inhibitor p27 Kip1 with induction of growth arrest and neural differentiation [ 327 , 328 ].

DNA-binding protein inhibitor ID-2 is a protein that in humans is encoded by the ID2 gene. [5] The protein encoded by this gene belongs to the inhibitor of DNA binding (ID) family, members of which are transcriptional regulators that contain a helix …

Mechanistically, through its HLH domain, Id2 binds and disrupts the assembly of the Tcf3-Tal1 transcriptional regulatory complex, and thus modulates chromatin accessibility at the Slamf6 promoter by preventing the interaction of Tcf3 with the histone lysine demethylase LSD1.

Apr 7, 2018 · The inhibitor of DNA binding and cell differentiation 2 (Id2) is a helix-loop-helix (HLH) protein that acts as negative dominant regulator of basic-HLH transcription factors during development and in cancer.

Oct 30, 2012 · We present the high-resolution 2.1Å crystal structure of ID2 (HLH domain), coupled with novel biochemical insights in the presence of a divalent ion, possibly calcium (Ca2+), in the loop of ID proteins, which appear to be crucial for the structure and activity of ID proteins.

Nov 2, 2023 · Inhibitor of DNA binding (ID) proteins, a group of Helix-Loop-Helix (HLH) transcription regulators, play a dominant role in regulating other HLH proteins (E proteins) required for the normal development of hematopoietic, muscle, neuronal, and other cells.

Nov 29, 2018 · Inhibitors of DNA binding (ID) proteins are critical actors in lymphopoiesis, acting as regulators of transcription through a helix-loop-helix (HLH) domain which enables heterodimerization with basic HLH (bHLH) proteins inhibiting their binding to DNA.

Inhibitor of binding or differentiation 2 (Id2), a member of helix-loop-helix (HLH) transcriptional factors, is recently reported as an important regulator of the development or differentiation of immune cells. It has been demonstrated that Id2 plays a critical role in the early lymphopoiesis.

Apr 19, 2022 · Phosphorylation of serine-5 by CDK1 prevented the association of ID2 with core APC, impaired ubiquitylation and stabilized ID2 protein at the mitosis-G1 transition leading to inhibition of basic Helix-Loop-Helix (bHLH)-mediated transcription.
