Alternate Names for Human Granzyme B DuoSet ELISA, 5 Plate
Background
Granzyme B is a member of the granzyme family of serine proteases found specifically in
granules of cytotoxic T lymphocytes (CTL) and natural killer (NK) cells (1, 2). Granzyme B plays
an essential role in granule-mediated apoptosis utilizing the substrates in this pathway, such as
Caspase 3, Caspase 8 and Bid (3, 4). Recent research indicates expanded Granzyme B
functionality to include extracellular roles along with its classical pro-apoptotic function. It has
been found that Granzyme B is an important mediator of skin injury, repair and inflammation
(4) through extracellular substrates including Laminin, VE-Cadherin, Fibronectin and the
proteoglycans Aggrecan (3) and Decorin (4).
As one of the five Granzymes (A, B, H, K and M) identified in the human genome, Granzyme B
(32kDa) (5) is the most widely researched in terms of its biological function and its utility in
health and disease (4). It is synthesized as a precursor (247 residues) with a signal peptide
(residues 1-18), a pro-peptide (residues 19-20), and a mature chain (residues 21-247) (6-8).
Once inside granules, Granzyme B is fully processed into the mature chain and becomes an
active protease when the pro-peptide, Gly-Glu is removed from the N-terminus by cleavage
with Cathepsin C (9). The protease activity of Granzyme B is tightly controlled by Serpin B9/
Protease Inhibitor 9 (9). The amino acid sequence of human Granzyme B is 71%, 69%, and 68%
identical to its canine, rat, and mouse counterparts, respectively.
Granzymes have been shown to modulate inflammation, and Granzyme B plasma levels have
been found higher with atopic dermatitis and psoriasis when compared to healthy controls.
This is in contrast to Granzyme A plasma levels which remain unchanged (10). Serum from
patients with Crohn's disease have significantly higher Granzyme B levels than controls (11).
