摘要

The present invention relates to a novel AIMP1 protein fragment and a composition for improving hair loss and promoting hair growth comprising the same as an active ingredient. More specifically, the present invention relates to a composition comprising 28 to 31 from the amino acid sequence represented by SEQ ID NO: 1. A polypeptide comprising 4 to 21 consecutive amino acids including the second amino acid (KEKA), or a polypeptide comprising an amino acid sequence having a sequence homology of 70% or more with the polypeptide. The present invention relates to a pharmaceutical, cosmetic, and food composition for improving hair loss and promoting hair growth, comprising the polypeptide; a polynucleotide encoding the polypeptide;
