Comments [?]

Function Component of the type III secretion system (T3SS), also called injectisome, which is used to inject bacterial effector proteins into eukaryotic host cells. Forms a ring-shaped multimeric structure with an apparent central pore in the outer membrane.
Subunit The core secretion machinery of the T3SS is composed of approximately 20 different proteins, including cytoplasmic components, a base, an export apparatus and a needle. This subunit is part of the base, which anchors the injectisome in the bacterial cell envelope. Forms a stable homooligomeric complex.
Subcellular location Cell outer membrane.
Similarity Belongs to the bacterial secretin family. T3SS SctC subfamily.

Comments A widely accepted unified nomenclature has been proposed for the components of the type III secretion system. Genes are called sct, for secretion and cellular translocation. See Hueck C.J. (PubMed:9618447, 1998) and t3sswiki.science.
