Here, we report the nucleotide (nt) sequence of the cDNA encoding the
sodium channel beta(1) subunit from rabbit (o beta 1). Cloning of the
o beta 1 cDNA was accomplished by reverse transcription-polymerase cha
in reaction using rabbit brain RNA as a template for cDNA synthesis. T
he nt sequence of the o beta 1 cDNA predicts a 218-amino-acid polypept
ide which is 96.3 and 97.3% identical to the beta(1) from human (h bet
a 1) and rat (r beta 1), respectively.
