Summary: The protein encoded by this gene belongs to the inhibitor of DNA binding family, members of which are transcriptional regulators that contain a helix-loop-helix (HLH) domain but not a basic domain. Members of the inhibitor of DNA binding family inhibit the functions of basic helix-loop-helix transcription factors in a dominant-negative manner by suppressing their heterodimerization partners through the HLH domains. This protein may play a role in negatively regulating cell differentiation. A pseudogene of this gene is located on chromosome 3. [provided by RefSeq, Aug 2011]

The study observed higher expression levels of HDGFRP3 and ID2 in bipolar disorder (BD) patients who favourably respond to lithium. Both of these genes are involved in neurogenesis.

ID2-AS1 significantly suppressed the migration, invasion and metastasis of hepatocellular carcinoma (HCC) cells in vitro and in vivo. Mechanistically, ID2-AS1 regulated the transcription of its adjacent gene inhibitor of DNA binding 2 (ID2) by blocking the binding of histone deacetylase 8 (HDAC8) on the ID2 enhancer
Title: LncRNA ID2-AS1 suppresses tumor metastasis by activating the HDAC8/ID2 pathway in hepatocellular carcinoma.
We have identified ID2 as a key factor of DCIS initiation and GJB2 and INHBA as aggressive factors during progression of ID2-mediated DCIS to IDC. ID2 is capable of promoting the cancer stem cell population in pre-malignant cells and leads to DCIS formation
Title: ID2 and GJB2 promote early-stage breast cancer progression by regulating cancer stemness.
Study identifies ID2 as a key regulator of breast cancer metastasis to the brain. Data support a model in which breast cancer cells that have disseminated to the brain upregulate ID2 expression in response to astrocyte-secreted BMP7 and this serves to support metastatic expansion. Moreover, elevated ID2 expression identifies breast cancer patients at increased risk of developing metastatic relapse in the brain.
Title: Using an in-vivo syngeneic spontaneous metastasis model identifies ID2 as a promoter of breast cancer colonisation in the brain.
Oxidative stress increased ID2 expression in retinal pigment epithelium (RPE) cells. Knockdown of ID2 promoted cell apoptosis and increased reactive oxygen species level in RPE cells that were subjected to oxidative damage. In addition, over-expression of ID2 attenuated the oxidative damage response in RPE cells.
Title: ID2 protects retinal pigment epithelium cells from oxidative damage through p-ERK1/2/ID2/NRF2.
The author's study identified a novel association with PR near ID2 and generalised 10 previously identified loci to our Hispanic/Latino population.

CaMKII can directly phosphorylate Beclin 1 at Ser90 to promote K63-linked ubiquitination of Beclin 1 and activation of autophagy; it also promotes K63-linked ubiquitination of inhibitor of differentiation 1/2 (Id-1/2) by catalyzing phosphorylation of Id proteins and recruiting TRAF-6
Title: CaMKII-mediated Beclin 1 phosphorylation regulates autophagy that promotes degradation of Id and neuroblastoma cell differentiation.
Results show that self-assembly decreases the backbone flexibility of ID2 protein regions: helix-loop-helix (HLH) and the nuclear export signal (NES), that are important for interaction with basic-HLH transcription factors or for nucleocytoplasmic shuttling.

the results of the present study suggest that lncRNA H19 regulates the expression of ID2 through competitive binding to hsamiR19a and hsamiR19b, which may serve a role in acute myelocytic leukemia cell proliferation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
