Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of, within or between cells. Transports a passenger protein from the periplasm to the external milieu; the passenger protein and the porin are the N- and C-terminal regions of the same protein, respectively. Enables the directed movement of a specific substance or group of related substances (such as macromolecules, small molecules, ions) into, out of, within or between cells. Enables the directed movement of proteins into, out of, within or between cells. Mediates the integration of proteins into a membrane from the inner side of the membrane. Membrane insertases are highly conserved and include the bacterial YidC family, the plant chloroplast Alb3 family, and the fungal and animal mitochondrial Oxa1/Cox18 family. Catalysis of the transfer of a protein from one side of a membrane to the other. Enables the directed movement of any conjugated, water-soluble protein in which the nonprotein moiety consists of a lipid or lipids, into, out of, within or between cells. Enables the directed movement of a glycoprotein, any protein that contains covalently bound glycose (i.e. monosaccharide) residues other than as a moiety of nucleic acid, into, out of, within or between cells. Interacting selectively and non-covalently with importin-alpha to mediate its transfer through the nuclear pore to the cytoplasm. Enables the directed movement of fully folded proteins into, out of, within or between cells by targeting the proteins to the transporter via a specialized N-terminal twin arginine signal peptide.
