Description

SUZ12 serves as an essential core component of Polycomb Repressive Complex 2 (PRC2), the multiprotein assembly responsible for catalyzing histone H3 lysine 27 trimethylation—a critical epigenetic mark that governs gene silencing during development and cellular differentiation. As a scaffold protein within PRC2, SUZ12 stabilizes the complex and is indispensable for its methyltransferase activity, making it a key focus for researchers investigating chromatin regulation, stem cell biology, and cancer epigenetics.

This recombinant monoclonal antibody, clone 1B10, offers the reproducibility and consistency that demanding epigenetic studies require. Generated against a synthetic peptide derived from human SUZ12 and produced using recombinant technology in rabbit, this antibody provides sequence-defined specificity with minimal lot-to-lot variation—particularly valuable for longitudinal studies or multi-site collaborations where experimental consistency is paramount.

Validation across multiple experimental platforms demonstrates this antibody's versatility in your workflow. Western blot analysis confirms robust detection in diverse human cell lines including HeLa, HepG2, MCF-7, HL60, THP-1, and K562, with an observed band at approximately 90 kDa. The slight shift from the predicted 84 kDa molecular weight likely reflects post-translational modifications such as glycosylation or phosphorylation events known to occur on SUZ12. Immunohistochemistry validation in paraffin-embedded human breast cancer tissue demonstrates clear nuclear staining patterns consistent with SUZ12's chromatin-associated function. Additionally, successful immunoprecipitation from K562 lysates confirms the antibody's utility for protein interaction studies and complex isolation.

Whether you're mapping PRC2 dynamics, investigating epigenetic dysregulation in disease models, or characterizing chromatin states, this antibody provides a reliable tool for advancing your research in epigenetics and nuclear signaling.

Target Background

Function

Polycomb group (PcG) protein. Component of the PRC2 complex, which methylates 'Lys-9' (H3K9me) and 'Lys-27' (H3K27me) of histone H3, leading to transcriptional repression of the affected target gene. The PRC2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. Genes repressed by the PRC2 complex include HOXC8, HOXA9, MYT1 and CDKN2A.

Involvement in disease

A chromosomal aberration involving SUZ12 may be a cause of endometrial stromal tumors. Translocation t(7;17)(p15;q21) with JAZF1. The translocation generates the JAZF1-SUZ12 oncogene consisting of the N-terminus part of JAZF1 and the C-terminus part of SUZ12. It is frequently found in all cases of endometrial stromal tumors, except in endometrial stromal sarcomas, where it is rarer.
