Transglutaminase 2

Art. No.

A034

Synonym

Monoclonal antibody to human TG2 (Beta Sheet Domain, clone XTG11)

Background info

Tissue transglutaminase is a, Ca2+-dependent enzyme (78 kDa) composed by 4 domains: Beta Sheet Domain (fibronectin binding, ~17 kDa), catalytic Core Domain (Cys-His-Asp catalytic triad, Calcium-binding, GTP/GDP-binding, ~37 kDa), Beta Barrel 1 Domain (GTP/GDP-binding, ~14 kDa) and Beta Barrel 2 Domain (~12 kDa). The inactive GTP-bound enzyme is present in a closed conformation, which upon activation by Ca2+ and substrate binding opens like a pocket knife resulting in a longitudinal open conformation (see figure). Figure: closed (left) and open (right) conformation of human tissue transglutaminase TG2 sequence deduced from TGM2 allele IMAGp958L121020 Epitopes in the above sequence are underlined and written in bold.

Host

Mouse

Clone

XTG11

Isotype

IgG2a (in previous PDS version given as IgG1)

Immunogen

Human tissue transglutaminase (full length protein with N-terminal hexahistidin-tag) recombinantly produced in insect cells

Specificity

Mouse monoclonal antibody binds to the Beta Sheet Domain of TG2. Specificity of A034 was determined in western blotting with human transglutaminases (TG1 – TG7, FXIII), TG2 of different species and human TG2 domains recombinantly produced in E. coli.  A034 is specific for the Beta Sheet Domain of TG2. It does not cross-react with other domains of human TG2.  A034 is specific for TG2. It does not cross-react with other human transglutaminases.  A034 is specific for human TG2. It does not cross-react with other TG2 from various species (human, guinea pig, rat, mouse and dog).
