Amino acid sequences facilitating penetration of a substance of interest into cells and/or cell nuclei

摘要

The present invention relates to an amino acid sequence being able to facilitate penetration of a substance of interest inside cells and/or cell nuclei and having the following formula : (X1)p Ä(X)o (B)n X B X X BÜm (X2)q Wherein X1 and X2 are amino acid sequences of 1 to 20 amino acids; p and q are whole numbers between 0 and 5; B is a basic amino acid; X is a non-basic, preferably hydrophobic amino acid, such as alanine, isoleucine, leucine, methionine, phenylalanine, tryptophan, valine or tyrosine; n is 2 or 3; o is 0 or 1.
