P63141 (KCNA2_MOUSE) Mus musculus (Mouse)

Potassium voltage-gated channel subfamily A member 2 UniProtKBInterproStringInteractive Modelling

499 aa; Sequence (Fasta) Identical sequences: Rattus norvegicus: P63142; Cricetulus griseus: A0A061INP0

Sequence Features

 252Important for normal, slow channel gating.
 381Important for binding with the scorpion mesomartoxin; when the scorpion mesomartoxin-rKv1.2/KCNA2 interaction is modeled, this residue is close to the 'Y- 57' residue of the toxin.
