Membrane proteins make up one third of all genes in the human genome. Computational structural modeling represents an important alternative to obtain three-dimensional membrane protein models at the atomic level. As the number of high-resolution membrane protein structures available increases, the template situation of the homology modeling program is rapidly improving, which ensures the high accuracy of the resulting model. The workflow for predicting membrane protein structure is applied to soluble membrane proteins, starting with the sequence alignment of the target protein with the selected template. During model construction, the structure of the transmembrane area is used as the core for prediction and constructed first.
CD ComputaBio adapts traditional homology modeling methods to predict the structure of membrane proteins, thereby avoiding any bias in the algorithm for soluble globular proteins and obtaining better modeling results. In the absence of structural information from closely related proteins, distant structural homologues can be used to reconstruct the core and loop regions. Over the years, we have accumulated extensive experience in modeling various types of membrane proteins, including G protein coupled receptors (GPCRs) and transporters. The generated structural models are all quality verified and can be used for drug design calculations, molecular dynamics simulations and to guide further experimental work, such as structure-based protein engineering.

Because there are too few membrane receptor proteins with known three-dimensional structures, structuring based on knowledge modeling is not reliable and subjective. With the accumulation of membrane protein structure data and the improvement of computer modeling methods, computational modeling will inevitably become more mature, and 3D structure construction more reliable. Once the three-dimensional structure model of the membrane receptor protein is obtained, it can be further reversed to guide experimental research, such as site mutation of the receptor and drug design based on the receptor structure.
The goal of the CD ComputaBio team is to predict the structure of the membrane protein from the amino acid sequence. Its accuracy is comparable to the experimental method and overcomes many difficulties in the determination of membrane protein structure.
