Ras association domain-containing protein 1 - Q9NS23 (RASF1_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Potential tumor suppressor. Required for death receptor-dependent apoptosis. Mediates activation of STK3/MST2 and STK4/MST1 during Fas-induced apoptosis by preventing their dephosphorylation. When associated with MOAP1, promotes BAX conformational change and translocation to mitochondrial membranes in response to TNF and TNFSF10 stimulation. Isoform A interacts with CDC20, an activator of the anaphase-promoting complex, APC, resulting in the inhibition of APC activity and mitotic progression. Inhibits proliferation by negatively regulating cell cycle progression at the level of G1/S-phase transition by regulating accumulation of cyclin D1 protein. Isoform C has been shown not to perform these roles, no function has been identified for this isoform. Isoform A disrupts interactions among MDM2, DAXX and USP7, thus contributing to the efficient activation of TP53 by promoting MDM2 self-ubiquitination in cell-cycle checkpoint control in response to DNA damage.

Subunit Structure
Interacts with MAP1S (PubMed:15205320, PubMed:15753381). Interacts with XPA (PubMed:10888881). Binds to the N-terminal of CDC20 during prometaphase (PubMed:14743218). Binds to STK3/MST2 and STK4/MST1 (PubMed:15109305, PubMed:16510573, PubMed:21199877). Isoform A interacts with MOAP1 (PubMed:15949439). Isoform A interacts with E4F1 (PubMed:14729613). Recruited to the TNFRSF1A and TNFRSF10A complexes in response to their respective cognate ligand, after internalization (PubMed:15949439). Can self-associate (PubMed:11857081). Isoform A interacts with RSSF5 and probably associates with HRAS via a RSSF1 isoform A-RSSF5 heterodimer (PubMed:11857081). Part of a complex with MDM2, DAXX, RASSF1 and USP7 (PubMed:18566590). Isoform A interacts (via C-terminus) with DAXX (via N-terminus); the interaction is independent of MDM2 and TP53 (PubMed:18566590). Isoform C or isoform H interacts (via N-terminus) with DAXX (PubMed:18566590). Isoform A interacts (via N-terminus) with MDM2 (via C-terminus); the interaction is independent of TP53 (PubMed:18566590). Interacts with ECM2 (By similarity). 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.
