  • Function
    Key component of PML nuclear bodies that regulate a large number of cellular processes by facilitating post-translational modification of target proteins, promoting protein-protein contacts, or by sequestering proteins. Functions as tumor suppressor. Required for normal, caspase-dependent apoptosis in response to DNA damage, FAS, TNF, or interferons. Plays a role in transcription regulation, DNA damage response, DNA repair and chromatin organization. Plays a role in processes regulated by retinoic acid, regulation of cell division, terminal differentiation of myeloid precursor cells and differentiation of neural progenitor cells. Required for normal immunity to microbial infections. Plays a role in antiviral response. In the cytoplasm, plays a role in TGFB1-dependent processes. Regulates p53/TP53 levels by inhibiting its ubiquitination and proteasomal degradation. Regulates activation of p53/TP53 via phosphorylation at 'Ser-20'. Sequesters MDM2 in the nucleolus after DNA damage, and thereby inhibits ubiquitination and degradation of p53/TP53. Regulates translation of HIF1A by sequestering MTOR, and thereby plays a role in neoangiogenesis and tumor vascularization. Regulates RB1 phosphorylation and activity. Required for normal development of the brain cortex during embryogenesis. Can sequester herpes virus and varicella virus proteins inside PML bodies, and thereby inhibit the formation of infectious viral particles. Regulates phosphorylation of ITPR3 and plays a role in the regulation of calcium homeostasis at the endoplasmic reticulum (By similarity). Regulates transcription activity of ELF4. Inhibits specifically the activity of the tetrameric form of PKM2. Together with SATB1, involved in local chromatin-loop remodeling and gene expression regulation at the MHC-I locus. Regulates PTEN compartmentalization through the inhibition of USP7-mediated deubiquitinylation.
  • Involvement in disease
    Note=A chromosomal aberration involving PML may be a cause of acute promyelocytic leukemia (APL). Translocation t(15;17)(q21;q21) with RARA. The PML breakpoints (type A and type B) lie on either side of an alternatively spliced exon.
  • Sequence similarities
    Contains 2 B box-type zinc fingers.
    Contains 1 RING-type zinc finger.
  • Domain
    Interacts with PKM2 via its coiled-coil domain.
    Binds arsenic via the RING-type zinc finger.
  • Post-translational
    Ubiquitinated; mediated by RNF4, SIAH1 or SIAH2 and leading to subsequent proteasomal degradation. 'Lys-6'-, 'Lys-11'-, 'Lys-48'- and 'Lys-63'-linked polyubiquitination by RNF4 is polysumoylation-dependent.
    Undergoes 'Lys-11'-linked sumoylation. Sumoylation on all three sites is required for nuclear body formation. Sumoylation on Lys-160 is a prerequisite for sumoylation on Lys-65. The PML-RARA fusion protein requires the coiled-coil domain for sumoylation. Desumoylated by SENP2 and SENP6. Arsenic induces PML and PML-RARA oncogenic fusion proteins polysumoylation and their subsequent RNF4-dependent ubiquitination and proteasomal degradation, and is used as treatment in acute promyelocytic leukemia (APL).
    Phosphorylated in response to DNA damage, probably by ATR.
    Acetylation may promote sumoylation and enhance induction of apoptosis.
  • Cellular localization
    Nucleus > nucleoplasm. Cytoplasm. Nucleus > PML body. Nucleus > nucleolus. Endoplasmic reticulum membrane. Early endosome membrane. Sumoylated forms localize to the PML nuclear bodies. The B1 box and the RING finger are also required for this nuclear localization. Isoforms lacking a nuclear localization signal are cytoplasmic. Detected in the nucleolus after DNA damage. Sequestered in the cytoplasm by interaction with rabies virus phosphoprotein.

Thank you for taking the time to complete our questionnaire and contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody.

The details you have kindly provided will enable us to investigate this case for you and also gives us vital information for our monitoring of product quality

I appreciate the time you have spent in the laboratory and understand your concerns. It is regrettable the results have not been successful. I would like to reassure you that this antibody is tested and covered by our guarantee forICC-IF and mouse samples.

Before deciding how to proceed with this particular case, I would like to offer some suggestions to help optimize the results. I would also appreciate if you can confirm some details of the procedure.

1. Could you confirm ifthe current vialofsecondary antibody is working well with other antibodies? It would be important to include a no primary control to assess if this is giving any background.

The speckled non specific fluorescence could be from aggregates of the conjugate. I can recommend to try spinning the vial of secondary verybriefly before using (to spin out aggregates).

The concentration of the secondarymay also need to be reduced in order to help optimize the results.

2. Dust on slides, or particles in the buffers can autofluorescence and can give a speckled staining appearance. I can suggest to ensure the slides and buffers are as clean as possible. Also, this could be caused by cell debris, and so I can recommend to ensure the cell culture sample is as healthy as possible.

3. I can recommend to fix for 10 minutes only to reduce the amount of protein crosslinking, which could affect staining.

4. For the wash steps, try washing in buffer containing 0.2% Tween 20. This will help to wash away any excess antibody. Also include 0.2% Tween 20 in the antibody dilution buffer.

In the event that a product is not functioning in the tested applications and species cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund.

I hope this information is helpful, thank you for your cooperation. Should the suggestions not improve the results, please do not hesitate to contact me again with the further requested information and details of how you would like to proceed.

Thank you for contacting us. The PML antibody ab53773 is raised against a peptide derived from the 20 amino acid range from aa35 to aa55 of human PML, Uniprot P29590 (PML_HUMAN). The exact sequence of the peptide is considered proprietary. http://www.Uniprot.org/uniprot/P29590 This peptide sequence is present in all isoforms of human PML listed in the Uniprot entry. Translocation to the nucleus is believed to be dependent on sumoylation of PML by SUMO-1, as discussed in the reference below. Assuming none of these modifications are to the immunogen sequence itself, antibody ab53773 should be capable of recognizing all isoforms, with and without these modifications, and so it should be capable of recognizing both nuclear and cytoplasmic PML. However, this has not to our knowledge been confirmed experimentally. J Cell Sci. 1999 Feb;112 ( Pt 3):381-93. SUMO-1 modification of the acute promyelocytic leukaemia protein PML: implications for nuclear localisation. PMID: 9885291 http://jcs.biologists.org/content/112/3/381.full.pdf I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
