Generic protein structure example


Two pore segment channel 1 (TPC1) is a human protein encoded by the TPCN1 gene.[1] 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 domains (each containing segments S1 to S6).[2][3][4]

Structure

The structure of a TPC1 ortholog from Arabidopsis thaliana has been solved by two laboratories.[5][6] The structures were solved using X-ray crystallography and contained the fold of a voltage-gated ion channel and EF hands. Only a single voltage sensor domain appears to responsible for voltage sensing.

Filoviral Infections

Genetic knockout and pharmacological inhibition experiments demonstrate that Two-pore Channels, TPC1 and TPC2, are required for infection by Filoviruses Ebola and Marburg in mice.[7]
