Voltage-gated calcium channel subunits from platyhelminths: Potential role in praziquantel action
2006
Jeziorski, M.C. | Greenberg, R.M.
Voltage-gated calcium (Ca2+) channels provide the pathway for Ca2+ influxes that underlie Ca2+-dependent responses in muscles, nerves and other excitable cells. They are also targets of a wide variety of drugs and toxins. Ca2+ channels are multisubunit protein complexes consisting of a pore-forming α1 subunit and other modulatory subunits, including the β subunit. Here, we review the structure and function of schistosome Ca2+ channel subunits, with particular emphasis on variant Ca2+ channel β subunits (Cavβvar) found in these parasites. In particular, we examine the role these β subunits may play in the action of praziquantel, the current drug of choice against schistosomiasis. We also present evidence that Cavβvar homologs are found in other praziquantel-sensitive platyhelminths such as the pork tapeworm, Taenia solium, and that these variant β subunits may thus represent a platyhelminth-specific gene family.
