The HDAC6 antibody is a critical research tool used to detect and study the histone deacetylase 6 (HDAC6) enzyme, a class IIb histone deacetylase with roles in chromatin remodeling, cytoskeleton regulation, and immune response modulation. This article provides a comprehensive overview of the HDAC6 antibody, including its structure, applications, and research findings, drawing from diverse scientific sources.
The HDAC6 antibody is a monoclonal or polyclonal immunoglobulin designed to bind specifically to the HDAC6 protein. Key structural details include:
Immunogen: Typically derived from synthetic peptides corresponding to regions of HDAC6, such as amino acid residues 1-16 (Active Motif) or near the C-terminal (Proteintech) .
Host/Isotype: Commonly mouse IgG1 (e.g., Proteintech 67250-1-Ig) or rabbit polyclonal (unspecified in sources) .
Molecular Weight: HDAC6 protein is approximately 114 kDa (calculated) but appears as 150-160 kDa in Western blot due to post-translational modifications .
HDAC6 regulates cytoskeleton dynamics, enabling viral transport and uncoating. Studies using HDAC6 antibodies have shown its involvement in innate immune responses against RNA/DNA viruses, including influenza .
Inhibition of HDAC6 activity increases CD20 surface expression in B-cell tumors, enhancing rituximab efficacy. Antibodies like those from Active Motif validate these effects in primary cells .
HDAC6 inhibition reduces tumor-associated M2 macrophages and enhances immune checkpoint blockade. Preclinical models using HDAC6 antibodies confirm its role in modulating the tumor microenvironment .
