Background:
Polycomb group (PcG) protein that specifically recognizes and binds mono- and dimethyllysine residues on target proteins, therey acting as a 'reader' of a network of post-translational modifications. PcG proteins maintain the transcriptionally repressive state of genes: acts as a chromatin compaction factor by recognizing and binding mono- and dimethylated histone H1b/HIST1H1E at 'Lys-26' (H1bK26me1 and H1bK26me2) and histone H4 at 'Lys-20' (H4K20me1 and H4K20me2), leading to condense chromatin and repress transcription. Recognizes and binds p53/TP53 monomethylated at 'Lys-382', leading to repress p53/TP53-target genes. Also recognizes and binds RB1/RB monomethylated at 'Lys-860'. Participates in the ETV6-mediated repression. Probably plays a role in cell proliferation. Overexpression induces multinucleated cells, suggesting that it is required to accomplish normal mitosis.
VALIDATION IMAGES
Immunoprecipitation was performed on nuclear extracts from cells transfected with FLAG-tagged L3MBTL1 (L3MBTL1-F) with the Bioss antibody against L3MBTL1 (Cat. No. bs-53097R) and with an IgG negative control antibody. Western Blot was performed with an anti-FLAG antibody to demonstrate the presence of L3MBTL1-F in the input (lane 1), in the precipitated fraction (P) and in the supernatant (SN). These data show that L3MBTL1-F was efficiently precipitated by the L3MBTL1 antibody (lane 3 and 5), whereas it was not precipitated by the IgG negative control antibody (lane 2 and 4).
Western blot was performed on nuclear extracts from HeLa cells (HeLa NE) using the Bioss antibody against L3MBTL1 (Cat. No. bs-53097R) diluted 1:1,000 in TBS-Tween containing 5% skimmed milk (lane 2). A molecular weight marker is shown in lane 1; the location of the protein of interest is indicated on the right.
