Small peptide modulators of potassium channel trafficking

Abstract

Provided herein are peptide modulators of ion channels. Specifically, the peptide modulators comprise the amino acid sequence VEDEC wherein V is valine, E is glutamate, D is aspartate, C is cysteine. In certain embodiments, the modulator is attached to the C-terminal end of Slo1 protein isoform. The present invention also claims conjugations of the first valine that make the peptide modulator more membrane permeable, such as myristoyl moieties and arginine-rich cell penetrating peptides. The present invention contemplates use of the peptide modulators in the treatment of diseases/malfunctions such as epilepsy, chronic pain, migraine, asthma, chronic obstructive pulmonary disease, urinary incontinence, hypertension, erectile dysfunction, irritable bowel syndrome, renal disorders of electrolyte imbalance, and possibly in certain kinds of cancer.
