| Expression | tissue and stage specifically expressed; expression is noted in embryonic, juvenile and adult tissues. The tissues or organs that express SUZ12 are: bladder, blood, bone, bone marrow, brain, cervix, colon, eye, heart, kidney, liver, lung, lymph node, mammary gland, muscle, ovary, pancreas, peripheral nervous system, placenta, prostate, skin, soft tissue, stomach, tongue, testis, uterus, and the vascular system. |

| Function | SUZ12 is a zinc finger protein and member of the polycomb group (PcG) protein family. They act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are required to maintain the repression during later stages of development. They probably act via the methylation of histones, rendering chromatin heritably changed in its expressibility. SUZ12 is a component of the PRC2 complex, which methylates Lys-9 and Lys-27 residues of histone H3. SUZ12 is induced by E2F1 transcription factor. |
