<p>A DNA sequence (I) encoding: (i) a polypeptide (II) with KCNQ5 activity; (ii) a polypeptide with the amino acid (aa) sequence of KCNQ5; (iii) a fully defined sequence (S2) of 932 aa as given in the specification; or (iv) derivatives of S2 with one or more aa deletions or exchanges, is new. Independent claims are also included for the following: (1) proteins encoded by (I); (2) host cells containing at least one (I); and (3) screening assay for identifying compounds (A) that modulate the activity of (II). - ACTIVITY : Neurological; cardiovascular; anticonvulsant. - MECHANISM OF ACTION : Modulation of the voltage-dependent KCNQ5 potassium channel, a key regulator of membrane potential and modulator of excitability of electrically activated cells such as neurons and cardiomyocytes. KCNQ5 may be implicated in some forms of epilepsy.</p> |
