• Bioactivity:

  Vm24-toxin (Vaejovis mexicanus peptide 24) TFA is a peptide composed of 36 amino acids, known for effectively and selectively blocking Kv1.3 channels, exhibiting an affinity (Kd) of approximately 3 pM in lymphocytes. It demonstrates over 1500 times greater affinity for Kv1.3 compared to other tested potassium channels. The structure of Vm24-toxin TFA includes a twisted cystine-stabilized ?/? motif, comprising a single-turn ?-helix and a three-stranded antiparallel ?-sheet, stabilized by four disulfide bridges. Additionally, Vm24-toxin TFA can attenuate the response of CD4+ effector memory T cells to T-cell receptor (TCR) stimulation.
