Abstract
Provided herein are polypeptides that bind to a blood-brain barrier (BBB) receptor, methods of generating such polypeptides, and methods of using the polypeptides to target a composition to a BBB receptor-expressing cell, e.g., for transport across the BBB. Also provided herein are transferrin receptor (TfR) constructs that comprise a monomeric TfR apical domain or one or more portions of the TfR apical domain which have been circularly permuted relative to the full-length TfR sequence.
