Function
Polycomb group (PcG) protein. Component of the PRC2/EED-EZH2 complex, which methylates 'Lys-9' (H3K9me) and 'Lys-27' (H3K27me) of histone H3, leading to transcriptional repression of the affected target gene. The PRC2/EED-EZH2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. Genes repressed by the PRC2/EED-EZH2 complex include HOXC8, HOXA9, MYT1 and CDKN2A. -
Tissue specificity
Overexpressed in breast and colon cancer. -
Involvement in disease
Note=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. -
Sequence similarities
Belongs to the VEFS (VRN2-EMF2-FIS2-SU(Z)12) family.
Contains 1 C2H2-type zinc finger. -
Developmental stage
Expressed at low levels in quiescent cells. Expression rises at the G1/S phase transition. -

Lanes 1 - 4: Merged signal (red and green). Green - ab12073 observed at 95 kDa. Red - loading control, ab8245, observed at 37 kDa.ab12073 was shown to specifically recognize SUZ12 in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when SUZ12 knockout samples were used. Wild-type and SUZ12 knockout samples were subjected to SDS-PAGE. ab12073 and ab8245 (loading control to GAPDH) were diluted to 1µg/mL and 1/10,000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

ab12073 was shown to react with SUZ12 in wild-type HeLa cells in western blot. The band observed in knockout cell line ab264983 (knockout cell lysate ab257721) lane below 95kDa may represent truncated forms and cleaved fragments. This has not been investigated further. Wild-type HeLa and SUZ12 knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab12073 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at a 1 µg/ml and a 1 in 20000 dilution respectively.
