Menin - O00255 (MEN1_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

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. UniProt

Subunit Structure
Component of the MLL-HCF complex, at least composed of KMT2A/MLL1, MEN1, ASH2L, RBBP5, DPY30, WDR5, HCFC1 and HCFC2. Component of the menin-associated histone methyltransferase complex, at least composed of KMT2B/MLL4, MEN1, ASH2L, RBBP5, DPY30 and WDR5. Interacts with POLR2B. Interacts with POLR2A phosphorylated at 'Ser-5', but not with the unphosphorylated, nor 'Ser-2' phosphorylated POLR2A forms. Interacts with FANCD2 and DBF4. Interacts with JUND (via MBM motif); inhibits the interaction of JUND with MAPK10 and the phosphorylation of JUND by MAP kinases MAPK8 and MAPK10 (PubMed:9989505, PubMed:22327296). Interacts with SMAD3, but not with SMAD2, nor SMAD4. Directly interacts with NFKB1, NFKB2 and RELA. Interacts with KMT2A (via MBM motif) (PubMed:25305204, PubMed:22936661, PubMed:22327296). The KMT2A-MEN1 complex interacts with PSIP1 with a greater affinity as MEN1 enhances interaction of KMT2A with PSIP1 (PubMed:25305204, PubMed:22327296). Interacts with the fusion protein KMT2A-MLLT3 (PubMed:25305204, PubMed:22936661). UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
