METHOD FOR MODULATING MUSCLE DIFFERENTIATION OR REGENERATION

摘要

Present invention relates to method for promoting or inhibiting muscle differentiation or regeneration using an enhancer or an inhibitor capable of modulating the binding of TAZ polypeptide with MyoD polypeptide; method for screening a substance capable of up- or down-regulating muscle differentiation or regeneration by use of interaction between TAZ polypeptide and MyoD polypeptide; an isolated peptide consisting of an amino acid sequence of SEQ ID NO. 2 which binds to and activates the MyoD polypeptide; a polynucleotide encoding the isolated peptide; and a pharmaceutical composition comprising the isolated peptide or the polynucleotide.
