Abundance of the Membrane Proteome in Yeast Cells Lacking Spc1, a Non-catalytic Subunit of the Signal Peptidase Complex
{{output}}
The signal peptidase complex (SPC) mediates processing of signal peptides of secretory precursors. But, recent studies show that the eukaryotic SPC also cleaves internal transmembrane segments of some membrane proteins, and its non-catalytic subunit, Spc1/SPCS... ...
