Q9WTU3 (SCN8A_MOUSE) Mus musculus (Mouse)

Sodium channel protein type 8 subunit alpha UniProtKBInterProSTRINGInteractive Modelling

1978 aa; Sequence (Fasta) ; (Isoform 2; Isoform 3; Isoform 4; Isoform 5; )

Sequence Features

 902Interchain; with SCN2B or SCN4B
 902Interchain; with the conotoxin GVIIJ (when the channel is not linked to SCN2B or SCN4B; the bond to SCN2B or SCN4B protects the channel from the inhibition by toxin)
 5V -> L
 1317A -> T (in medjo)
