Signal peptidase complex subunit 2 (SPCS2)

Signal peptidase complex subunit 2 (SPCS2) is a protein-coding gene that encodes a component of the signal peptidase complex (SPC) located in the membrane of the endoplasmic reticulum[1][5][8]. The SPC catalyzes cleavage of N-terminal signal sequences from nascent proteins during their translocation into the endoplasmic reticulum lumen, a critical step in the maturation and secretion of many proteins[2][3][4]. SPCS2 enhances and facilitates the enzyme activity of the complex, and is conserved across species. Mutations or dysregulation may be involved in diseases such as spinocerebellar ataxia 13 and have roles in infectious disease-related pathways[1][5]. No drugs are currently reported to directly interact with or target SPCS2, and there are no established clinical biomarkers or safety issues specifically tied to this entity.
