label: MH2 domain binding
label_lc: mh2 domain binding
description: "Binding to a MH2 (MAD homology 2) protein domain. The MH2 domain is found at the carboxy-terminus of MAD related proteins such as Smads. The MH2 domain mediates interaction with a wide variety of proteins and provides specificity and selectivity to Smad function and also is critical for mediating interactions in Smad oligomers."
