Biological Activity
dynamin inhibitory peptide is a peptide (gln-val-pro-ser-arg-pro-asn-arg-ala-pro) inhibitor of the gtpase dynamin.dynamin is a 100-kda large gtpase that functions to tabulate membranes and liberate nascent vesicles from the golgi apparatus and plasma membrane. dynamin also plays a role in many processes including division of organelles,cytokinesis and microbial pathogen resistance.dynamin inhibitory peptide competitively blocks binding of dynamin to amphiphysin thus prevents endocytosis when administered intracellularly. reduces gabaa receptor internalization and increases miniature ispc amplitude and frequency in neurons expressing gabaa receptors.figure1 formula of dynamin inhibitory peptide
