Memoir is a homology modelling algorithm designed for membrane proteins. The inputs are the sequence which is to be modelled, and the 3D structure of a template membrane protein. We have a short video tutorial on how to use Memoir and an example results page. We also have a tutorial on how to model multiple chain transmembrane proteins.

Memoir integrates our membrane protein software programs:

Target sequence* Upload the .fasta (or .fas, .faa, .fa, .txt) file of the sequence of the membrane protein you want to model. Or, alternatively, you can paste the protein sequence (header is optional) in the text box provided.
