Functional Annotations
Enzyme classification and Gene Ontology terms linked to this protein.
Gene Ontology (GO)
8- GO:0031522 A transmembrane protein complex involved in the translocation of proteins across the cytoplasmic membrane. In Gram-negative bacteria, Sec-translocated proteins are subsequently secreted via the type II, IV, or V secretion systems. Sec complex components include SecA, D, E, F, G, Y and YajC.
- GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
- GO:0008320 Enables the transfer of a protein from one side of a membrane to the other.
- GO:0005048 Binding to a signal sequence, a specific peptide sequence found on protein precursors or mature proteins that dictates where the mature protein is localized.
- GO:0043952 The process in which unfolded proteins are transported across the cytoplasmic membrane in Gram-positive and Gram-negative bacteria by the Sec complex, in a process involving proteolytic cleavage of an N-terminal signal peptide.
- GO:0006616 The process during cotranslational membrane targeting wherein proteins move across a membrane. SRP and its receptor initiate the transfer of the nascent chain across the endoplasmic reticulum (ER) membrane; they then dissociate from the chain, which is transferred to a set of transmembrane proteins, collectively called the translocon. Once the nascent chain translocon complex is assembled, the elongating chain passes directly from the large ribosomal subunit into the centers of the translocon, a protein-lined channel within the membrane. The growing chain is never exposed to the cytosol and does not fold until it reaches the ER lumen.
- GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
- GO:0015031 The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

PDB and ChEMBL records on this protein are shown in full. ChEMBL records from similar proteins are capped at the top 100 per protein (by pchembl) and ZINC at the top 50 (Tanimoto ≥ 0.5). ADME columns are descriptor-based screening flags, not experimental toxicity results.
