ICAM4 Antibody

What is ICAM4 and why is it significant for immunological research?

ICAM4 (Intercellular Adhesion Molecule 4), also known as the Landsteiner-Wiener blood group, is a unique member of the ICAM family specifically expressed on erythroid cells. It consists of 271 amino acid residues with a molecular mass of approximately 29.3 kDa in its canonical form . ICAM4's significance stems from its role in cell adhesion and its ability to interact with multiple integrin types expressed on blood and endothelial cells . The protein is localized to the cell membrane and is also secreted, with up to three different isoforms reported . ICAM4 serves as a crucial mediator in maintaining red blood cell stability and flexibility during circulation, enabling these cells to navigate through capillaries without significant issues . Its study is particularly valuable for understanding erythrocyte function, cellular adhesion mechanisms, and potential implications in hematological disorders.

What are the most reliable applications for ICAM4 antibody detection?

Based on established research protocols, the most reliable applications for ICAM4 antibody detection include:

• Western Blot: Consistently detects ICAM4 with specific bands observed at approximately 42-48 kDa in human erythrocytes and heart tissue samples . This technique works effectively under reducing conditions using appropriate immunoblot buffer systems.

• Immunohistochemistry (IHC-P): Successfully demonstrates membrane staining in formalin-fixed, paraffin-embedded tissues, particularly in human fetal colon tissue at dilutions around 1/100 .

Following these guidelines ensures accurate quantification of ICAM4 expression on red blood cells and erythroid progenitors.

How does ICAM4 function as a ligand for integrin receptors and what are the implications for experimental design?

ICAM4 serves as a ligand for multiple integrin receptors with significant functional implications:

• Integrin binding profile: ICAM4 interacts with leukocyte adhesion protein LFA-1 (integrin alpha-L/beta-2), alpha-4/beta-1, alpha-V integrins, and notably functions as a ligand for monocyte/macrophage-specific CD11c/CD18 .

• Domain-specific interactions: Both immunoglobulin domains of ICAM4 contain binding sites for CD11c/CD18, with distinct but spatially related residues involved in these interactions . This domain architecture necessitates careful epitope selection when designing blocking experiments.

• Functional consequences: These interactions appear critical for erythrophagocytosis processes, particularly in the removal of senescent red cells by macrophages in the spleen and bone marrow .

• Experimental implications:

  • Blocking studies should target specific domains depending on which integrin interaction is being investigated

  • Point mutation analysis can identify critical binding residues that cluster in specific regions

  • Both domains must be considered when designing inhibitory strategies

  • Synthetic peptides derived from ICAM4 sequences can modulate binding to specific integrins

• Molecular modeling considerations: Important residues cluster in two distinct but spatially close regions of the first domain with an extension to the second domain that is spatially distant from other residues .

Understanding these interactions guides experimental approaches for studying erythrocyte-macrophage interactions, particularly in contexts of red cell turnover and pathological conditions affecting erythrocyte clearance.

What are the most effective methods for investigating ICAM4's role in erythrophagocytosis?

Investigating ICAM4's role in erythrophagocytosis requires specialized methodological approaches:

• Antibody blocking experiments: Use antibodies against both ICAM-4 and its integrin partners (particularly CD11c/CD18) to inhibit erythrophagocytosis in controlled systems. This approach has successfully demonstrated ICAM4's functional involvement in senescent red cell removal .

• Peptide competition assays: Employ synthetic peptides derived from ICAM4 sequences that have been shown to modulate binding to CD11c/CD18. Two specific peptides identified in research effectively modulate this interaction and can be used to probe functional significance .

• Domain deletion analysis: Utilize deletion constructs of individual immunoglobulin domains of ICAM4 to identify which regions are critical for interactions with phagocytic cells .

• Point mutation studies: Implement site-directed mutagenesis to modify specific residues identified as important for integrin binding, followed by functional assays to assess the impact on phagocytosis .

• Ex vivo phagocytosis assays: Develop controlled systems using isolated splenic or bone marrow macrophages and labeled erythrocytes (either artificially aged or collected at different stages of their lifespan).

• In vivo tracking studies: Track the clearance of labeled erythrocytes in animal models where ICAM4 or its receptors have been manipulated through genetic or pharmacological approaches.

These methodologies, especially when used in combination, provide robust systems for investigating the molecular mechanisms underlying ICAM4's role in erythrocyte clearance processes.

How can researchers investigate post-translational modifications of ICAM4 and their impact on antibody recognition?

Investigating post-translational modifications (PTMs) of ICAM4, particularly O-glycosylation , requires specialized approaches:

• Antibody epitope mapping:

  • Use synthetic peptide arrays representing ICAM4 sequences to map precise antibody binding regions

  • Compare binding to glycosylated versus non-glycosylated peptides

  • Implement methods similar to the membrane-bound peptide approach with 15 amino acid overlapping sequences

Understanding PTMs is crucial as they may significantly affect antibody recognition, potentially explaining the variable molecular weight observations between different detection methods (42 kDa in standard Western blot versus 48 kDa in Simple Western detection) .

How should researchers interpret discrepancies in molecular weight detection of ICAM4?

When encountering molecular weight discrepancies in ICAM4 detection, consider these interpretive frameworks:

• Expected variation range: ICAM4 typically appears between 42-48 kDa in reducing conditions, with specific observations of:

  • 42 kDa in standard Western blot of human erythrocytes and heart tissue

  • 48 kDa in Simple Western analysis of human heart tissue

  • 29.3 kDa theoretical molecular weight for the canonical protein

• Sources of variation:

  • Post-translational modifications: O-glycosylation significantly impacts apparent molecular weight

  • Detection method differences: Simple Western versus traditional Western blot methodologies employ different separation principles
