Two pore segment channel 1 (TPC1) is a human protein encoded by the TPCN1 is a human gene. The protein encoded by this gene is an ion channel. In contrast to other calcium and sodium channels which have four homologous domains each containing 6 transmembrane segments (S1 to S6) TPCN1 only contains two domain (each containing segments S1 to S6).
