MoRFs
Molecular Recognition Features (MoRFs) are small (10-70 residues) intrinsically disordered regions in proteins that undergo a disorder-to-order transition upon binding to their partners. MoRFs are implicated in protein-protein interactions, which serve as the initial step in molecular recognition. MoRFs are disordered prior binding to their partners, whereas they form a common 3D structure after interacting with their partners.[1][2]
Amino Acid composition
Their amino acid composition is very interesting. They look like disordered proteins, but they have some characteristics of ordered proteins.[2]
Categorization
MoRFs can be separated in 4 categories according to the shape they form once bound to their partners.[2]
The categories are:
- α-MoRFs (when they form alpha-helixes)
- β-MoRFs (when they form beta-sheets)
- irregular-MoRFs (when they don't form any shape)
- complex-MoRFs (combination of the above categories)
