Polypeptide comprising cell-penetrating sequence and composition comprising same

Abstract

The present application provides: a polypeptide characterized by having an ability of penetrating into a cell and the structure represented by Formula (I) wherein n is a number of 2 to 20; R1 and R2 may independently represent a C1-C4 alkyl group or may bind to each other to form a ring; R3 represents a C1-C10 primary aminoalkyl group; R4 represents a hydrogen atom or a C1-C10 hydrocarbon group; the “n” number of R1, R2, R3, and R4 may independently be the same with or different from each other; and the N-terminus and the C-terminus may or may not be modified independently; and a cell-invasive composition comprising the polypeptide and a substance of interest.
