Supplementary information

Granzyme A also known as CTLA3 or GZMA is a serine protease with a role in immune cell-mediated cytotoxicity. It has a molecular weight of approximately 27 kDa. This protein is primarily expressed in the granules of cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells. Granzyme A gets released into the immunological synapse upon recognition of target cells by these immune cells facilitating the induction of target cell death.
Biological function summary

Functions of Granzyme A extend to inducing apoptosis in target cells alongside its role in promoting inflammation. It operates independent of caspases and directly cleaves substrates in the cell to induce cell death making it different from the related Granzyme B. As part of the granzyme-perforin complex it enters target cells via perforin-created pores mediates reactions leading to substrate degradation and promotes DNA damage.

Pathways

Granzyme A gets involved in the granule exocytosis pathway which constitutes an important mechanism for CTLs and NK cells to kill infected or cancerous cells. The protein is also linked to the inflammatory response pathways where it can interact with other serine proteases. Related proteins like perforin and Granzyme B also engage in these pathways and they collectively work to trigger apoptosis and modulate immune responses.

Impairments or dysregulation of Granzyme A function can contribute to autoimmune diseases and certain viral infections. Autoimmune diseases such as lupus may demonstrate altered levels or activity of Granzyme A associated with tissue damage and inflammation. During viral infections Granzyme A in conjunction with perforin and Granzyme B aids in eliminating infected cells but alterations in this balance could lead to ineffective immune responses or excessive tissue damage.

Target data

Abundant protease in the cytosolic granules of cytotoxic T-cells and NK-cells which activates caspase-independent pyroptosis when delivered into the target cell through the immunological synapse (PubMed : 12819770, PubMed : 32299851, PubMed : 3257574, PubMed : 3262682, PubMed : 3263427). It cleaves after Lys or Arg (PubMed : 12819770, PubMed : 32299851). Once delivered into the target cell, acts by catalyzing cleavage of gasdermin-B (GSDMB), releasing the pore-forming moiety of GSDMB, thereby triggering pyroptosis and target cell death (PubMed : 32299851, PubMed : 34022140, PubMed : 36157507, PubMed : 36899106). Cleaves APEX1 after 'Lys-31' and destroys its oxidative repair activity (PubMed : 12524539). Cleaves the nucleosome assembly protein SET after 'Lys-189', which disrupts its nucleosome assembly activity and allows the SET complex to translocate into the nucleus to nick and degrade the DNA (PubMed : 11555662, PubMed : 12628186, PubMed : 16818237).
