Abstract: Compositions and methods are directed to engineered extracellular matrix protein—mussel foot protein fusions for use as a bioadhesive for repairing tissues. The compositions have one or more of: (i) at least one hydrophobic region; (ii) at least one crosslinking region; (iii) at least one tyrosine residue accessible to be enzymatically modified to a DOPA or TOPA side chain; (iv) at least one mussel foot protein; (v) at least one mussel foot protein loop; (vi) at least one human extracellular protein loop; or (vii) at least one of the following sequences: SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, or SEQ ID NO: 6. The elastin-like polypeptide includes at least one non-naturally occurring amino acid or sequence alteration.
