SEC11C, a member of the SEC11 protease family, is a critical component of the signal peptidase complex (SPC) in eukaryotic cells. This complex resides in the endoplasmic reticulum (ER) and is responsible for cleaving N-terminal signal peptides from nascent secretory and membrane proteins during their translocation into the ER lumen. SEC11C, also known as SPC18 or SEC11C, functions as one of the catalytic subunits of the SPC, working alongside other subunits like SEC11A (SPC21) and SEC11B (SPC22/23) to ensure precise cleavage of signal sequences—a step essential for proper protein folding, trafficking, and function.
Recombinant SEC11C protein is engineered for in vitro studies to dissect its enzymatic activity, substrate specificity, and regulatory mechanisms. Produced typically in heterologous expression systems (e.g., E. coli or mammalian cells), the recombinant form often includes affinity tags (e.g., His-tag) for purification. Its applications span basic research, including investigations into ER-associated protein processing, secretory pathway dysregulation in diseases (e.g., cancer, neurodegenerative disorders), and drug discovery targeting signal peptidase activity. Additionally, it serves as a tool to study pathogen-host interactions, as some pathogens exploit the host SPC for protein maturation. Despite its specialized role, SEC11C’s recombinant availability has accelerated structural and functional studies, offering insights into ER biology and therapeutic strategies for secretion-related pathologies.
