ASC (apoptosis-associated speck-like protein containing a CARD), also known as TMS1 (target of methylation-induced silencing), was first identified in 1999 as a protein that forms aggregates, or specks, during retinoic acid-induced apoptosis in a human leukemia cell line (1). Furthermore, it was discovered to have a role as a tumor suppressor as methylation silences ASC/TMS1 expression in many tumors (2-5). ASC/TMS1 is synthesized as a 195-amino acid (aa) protein with a theoretical weight of 22 kDa. Structurally the protein contains a N-terminal PYD (pyrin domain) and C-terminal CARD (caspase-recruitment domain) (1-4). Historically, CARD and PYD-containing proteins are known to have crucial functions in regulating apoptosis and immune response pathways (2-5). Furthermore, mutations in many CARD and PYD-containing proteins have been linked to various cancers and inflammatory diseases (2-5). Given its immune response role, it is not surprising that ASC/TMS1 is typically highly expressed in immune cells, specifically in neutrophils and cells of the macrophage/monocyte lineage (5). Additionally, it is expressed in many normal epithelial cell types (4,5).

In regard to immune and inflammatory response, ASC/TMS1 is involved in inflammasome function (3-4). The inflammasome is a multiprotein complex that responds to cellular stress or pathogens and activates inflammatory responses. Specifically, ASC/TMS1 helps assemble the NLRP3 inflammasome complex which then activates caspase-1, followed by stimulation of proinflammatory cytokines including IL-1b and IL-18 (3-4). In terms of the role in regulating apoptosis, multiple studies have revealed that the ASC/TMS1 gene is hypermethylated in many cancers including breast, lung, glioblastomas, and melanomas (2-5). The increased methylation results in decreased gene expression, or silencing, allowing those cancer cells to escape apoptosis (2-5).
