The p Subunit Genes

Voltage-gated Na channels isolated from mammalian central and peripheral neurons and cardiac myocytes are heterotrimeric complexes composed of a, 1, and P2 subunits (Catterall 1992, Malhotra et al 2001). 0 and ) 1 subunits have also been identified in skeletal muscle (Trimmer et al 1989, Yang et al 1993) while 2 has not. The a subunits encode a small gene family of at least 10 members (Plummer Meisler 1999). Recently, two additional members of the P subunit gene family, pi A 124... 

Camptotheca acuminata. Comparison of the two differentially regulated genes encoding the AS a-subunit showed that the spatial and developmental expression of only one paralleled that of the p-subunit gene and the pattern...
