  Domain Name: MH2
C-terminal Mad Homology 2 (MH2) domain. The MH2 domain is found in the SMAD (small mothers against decapentaplegic) family of proteins and is responsible for type I receptor interactions, phosphorylation-triggered homo- and hetero-oligomerization, and transactivation. It is negatively regulated by the N-terminal MH1 domain which prevents it from forming a complex with SMAD4. The MH2 domain is multifunctional and provides SMADs with their specificity and selectivity, as well as transcriptional activity. Several transcriptional co-activators and repressors have also been reported to regulate SMAD signaling by interacting with the MH2 domain. Mutations in the MH2 domains of SMAD2 and especially SMAD4 have been detected in colorectal and other human cancers.
No pairwise interactions are available for this conserved domain.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
