Supplier: Medchemexpress LLC HYP5917A1MG
Vm24-toxin (Vaejovis mexicanus peptide 24) is a 36-residue peptide that acts as a potent and selective Kv1.3 blocker with a Kd of approximately 3 pM in lymphocytes. It exhibits over 1500-fold higher affinity for Kv1.3 compared to other assayed potassium channels. Vm24-toxin possesses a distorted cystine-stabilized α/β motif, comprising a single-turn α-helix and a three-stranded antiparallel β-sheet, stabilized by four disulfide bridges. This peptide can attenuate the CD4+ effector memory T cell response to T cell receptor (TCR) stimulation.
