Function
DNA-binding protein inhibitor ID-1 is a protein that in humans is encoded by the ID1 gene. The protein encoded by this gene is a helix-loop-helix (HLH) protein that can form heterodimers with members of the basic HLH family of transcription factors. The encoded protein has no DNA binding activity and therefore can inhibit the DNA binding and transcriptional activation ability of basic HLH proteins with which it interacts. This protein may play a role in cell growth, senescence, and differentiation. Two transcript variants encoding different isoforms have been found for this gene. ID1 has been shown to interact weakly with MyoD but very tightly with ubiquitously expressed E proteins. E proteins heterodimerize with tissue restricted bHLH proteins such as Myod, NeuroD, etc. to form active transcription complexes so by sequestering E proteins, Id proteins can inhibit tissue restricted gene expression in multiple cell lineages using the same biochemical mechanism. Other interacting partners include CASK. ID1 can be used to mark endothelial progenitor cells which are critical to tumor growth and angiogenesis. Targeting ID1 results in decreased tumor growth. ID1 has been shown to be targeted by cannabidiol in certain gliomas and breast cancers.

Western blot analysis of Id1 on 293T cell lysates with Rabbit anti-Id1 antibody (ET1705-49) at 1/500 dilution.
Lysates/proteins at 10 µg/Lane.
Predicted band size: 16 kDa
Observed band size: 22 kDa
Exposure time: 2 minutes;
15% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (ET1705-49) at 1/500 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1:300,000 dilution was used for 1 hour at room temperature. -

Immunocytochemistry analysis of HeLa cells labeling Id1 with Rabbit anti-Id1 antibody (ET1705-49) at 1/100 dilution.
Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-Id1 antibody (ET1705-49) at 1/100 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488, HA1121) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.
