FunctionTestis-specific DNA binding protein responsible for insulator function, nuclear architecture and transcriptional control, which probably acts by recruiting epigenetic chromatin modifiers. Plays a key role in gene imprinting in male germline, by participating in the establishment of differential methylation at the IGF2/H19 imprinted control region (ICR). Directly binds the unmethylated H19 ICR and recruits the PRMT7 methyltransferase, leading to methylate histone H4 'Arg-3' to form H4R3sme2. This probably leads to recruit de novo DNA methyltransferases at these sites (By similarity). Seems to act as tumor suppressor. In association with DNMT1 and DNMT3B, involved in activation of BAG1 gene expression by binding to its promoter. Required for dimethylation of H3 lysine 4 (H3K4me2) of MYC and BRCA1 promoters.
Tissue specificityTestis specific. Specifically expressed in primary spermatocytes.
Sequence similaritiesBelongs to the CTCF zinc-finger protein family.
Contains 11 C2H2-type zinc fingers.
Developmental stageIs up-regulated in primary spermatocytes (expression overlapping with the genome-wide erasure of methylation) to become silenced on activation of CTCF in post-meiotic germline cells (expression corresponding to DNA remethylation).
Cellular localizationCytoplasm. Nucleus.

ICC/IF image of ab111255 stained MCF7 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab111255, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96887, DyLight® 488 goat anti-rat IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% formaldehyde fixed (10 min) HeLa and HepG2 cells at 10µg/ml, and in 100% methanol fixed (5 min) Hek293 cells at 10µg/ml.
