  • Function
    Essential component of a MLL/SET1 histone methyltransferase (HMT) complex, a complex that specifically methylates 'Lys-4' of histone H3 (H3K4). Functions as a transcriptional regulator. Binds to the TERT promoter and represses telomerase expression. Plays a role in TGFB1-mediated inhibition of cell-proliferation, possibly regulating SMAD3 transcriptional activity. Represses JUND-mediated transcriptional activation on AP1 sites, as well as that mediated by NFKB subunit RELA. Positively regulates HOXC8 and HOXC6 gene expression. May be involved in normal hematopoiesis through the activation of HOXA9 expression (By similarity). May be involved in DNA repair.
  • Tissue specificity
  • Involvement in disease
    Defects in MEN1 are the cause of familial multiple endocrine neoplasia type I (MEN1) [MIM:131100]. Autosomal dominant disorder characterized by tumors of the parathyroid glands, gastro-intestinal endocrine tissue, the anterior pituitary and other tissues. Cutaneous lesions and nervous-tissue tumors can exist. Prognosis in MEN1 patients is related to hormonal hypersecretion by tumors, such as hypergastrinemia causing severe peptic ulcer disease (Zollinger-Ellison syndrome, ZES), primary hyperparathyroidism, and acute forms of hyperinsulinemia.
    Defects in MEN1 are the cause of familial isolated hyperparathyroidism (FIHP) [MIM:145000]; also known as hyperparathyroidism type 1 (HRPT1). FIHP is an autosomal dominant disorder characterized by hypercalcemia, elevated parathyroid hormone (PTH) levels, and uniglandular or multiglandular parathyroid tumors.
  • Post-translational

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast carcinoma tissue labelling Menin with ab2605 at 1/1000 (1µg/ml). Detection: DAB.
  • Detection of menin in 293 cells using ab2605 (2ug/ml). Secondary antibody is Cy3 conjugated anti rabbit IgG.
  • Ab2605 staining Human normal placenta. Staining is localized to the nucleus.
    Left panel: with primary antibody at 4 ug/ml. Right panel: isotype control.
    Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS), then incubated with primary antibody for 20 minutes, and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

Thank you for contacting us.

I have looked into whether the anti-Menin antibody (ab2605)would be suitable for the experiments you are hoping to perform. Unfortunately, the immunogen used to raise this antibody is directed against the C-terminal end of human Menin. Through epitope mapping it has been established that the antibody specifically recognises a region betweenresidue 575 and theC-terminus (residue 615) of Menin. This antibody would therefore not be suitable if you are hoping todetect the regionN-terminal of residue 575.

I have however been able to find two other antibodies which we have been raised against peptidesderived from the N-terminal sequence of Menin which may be suitable for you.Ab32963 and ab75923 are both rabbit polyclonals which have been used in Western blotting.A blocking peptide is also available for ab32963, the catalogue code for this is ab32962.

I hope this information has been of help. If you require any further information please do not hesitate to ask.

Thank you for your enquiry. The epitope recognized by ab2605 maps to a region between residue 575 and the C-terminus (residue 615) of human Multiple Endocrine Neoplasia 1 using the numbering given in entry NP_000235.2 (GeneID 4221). Unfortunately, the exact sequence information is proprietary. I hope this information will still be helpful. If there is anything else that I can help you with, please do not hesitate to contact me.

Thank you for your enquiry and my apologies for the delay in replying to you, I have just received further information from the lab to answer your questions. We are not sure of the exact dilution used for the image on the datasheet, it is between 1/1000 - 1/10000 and I would recommend to try a range of dilution when you do the preliminary experiments to determine optimal conditions. The secondary is a standard HRP conjugated anti rabbit antibody. The reference on the datasheet was indeed incorrect, however I found the following references which are specific for this antibody: Milne TA et al. Menin and MLL cooperatively regulate expression of cyclin-dependent kinase inhibitors. Proc Natl Acad Sci U S A 102:749-54 (2005). PubMed: 15640349 Yokoyama A et al.
