Protein translocase subunit secY/sec61 alpha; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10.

The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.
