Transglutaminase 2

Art. No.

A033

Synonym

Monoclonal antibody to human TG2 (Catalytic Domain, clone XTG17)

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)TG2 sequence deduced from TGM2 allele IMAGp958L121020 Epitopes in the above sequence are underlined and written in bold.

Host

Mouse

Clone

XTG17

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 catalytic Catalytic Domain of TG2 (human, guinea pig, rat, mouse and dog TG2). Specificity of A033 was determined in western blotting with human transglutaminases (TG1 – TG7, FXIII), TG2 of different species and human TG2 domains recombinantly produced in E. coli.  A033 is specific for the Catalytic Domain of TG2. It does not cross-react with other domains of human TG2.  A033 is specific for TG2. It does not cross-react with other human transglutaminases.  A033 recognizes human, guinea pig, rat, mouse, and to a weak extend dog TG2.

Appearance

liquid

Description

The IgG fraction was purified by ion exchange chromatography.
