Objective:
To analyze the secondary structure of connective tissue growth factor (CTGF) for the prediction and screening of candidate receptor-binding domain of CTGF.
Methods:
Bioinformatics method was employed to predict and screen CTGF receptor-binding domain based on the analysis of secondary structure of CTGF, and its hydrophilicity and physical property.
Results:
The results showed that the candidate receptor-binding domains locate in 96-102, 104-112, 257-272 segments, the corresponding amino acid sequences are TAKDGAP, IFGGTVYRS and IRTPKISKPIKFELSG, respectively.
Conclusion:
There were 3 candidate receptor-binding domains of CTGF, which might be the targets for newly antagonistic micromolecule polypeptide of CTGF.

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
Conserved Binding Sites
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally analyses the...
