IDM2 Antibody

IDM2 Protein Overview

IDM2 (Increased DNA Methylation 2) is an α-crystallin domain protein identified in Arabidopsis thaliana that interacts with IDM1 to regulate active DNA demethylation and prevent transcriptional silencing . Key findings include:

• Function: IDM2 maintains genomic hypomethylation by promoting H3K18 acetylation, a critical epigenetic modification .

• Genetic Impact: Mutations in IDM2 lead to hypermethylation at thousands of loci, silencing endogenous genes such as ROS1 .

• Subcellular Localization: IDM2 colocalizes with IDM1 at discrete nuclear foci, suggesting cooperative activity .

Antibodies Targeting ID2 (Inhibitor of DNA Binding 2)

While no direct data exists for an "IDM2 Antibody," research on the structurally similar ID2 antibody (e.g., clone ILCID2) is well-documented:

• Applications:

  • Flow cytometry (mouse/human ID2 detection) .

  • Nuclear staining using Foxp3/Transcription Factor Buffer Sets .

• Biological Role:

  • ID2 regulates immune cell development (e.g., NK cells, T-cells) by inhibiting E-protein transcription factors .

Research Gaps and Ambiguities

• IDM2 vs. ID2: No studies in the provided sources describe an antibody specific to plant IDM2. The term may conflate IDM2 (plant) with ID2 (mammalian), a distinct protein.

• Clinical Relevance: ID2 antibodies are used in immunology research, whereas IDM2’s role remains confined to plant epigenetics .

Comparative Analysis of Antibody Applications

Future Directions

• Antibody Development: Generating IDM2-specific antibodies could advance plant epigenetics research.

• Cross-Species Studies: Investigating whether IDM2 homologs exist in mammals may bridge gaps in understanding epigenetic regulation.
