Product Type Specific: TGM2 phosphosite-specific antibody
Antibody Code: PN541
Antibody Target Type: Phosphosite-specific
Antibody Phosphosite: Y369
Protein UniProt: P21980
Protein SigNET: TGM2
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human TGM2 sequence peptide Cat. No.: PE-04ADQ95
Antibody Immunogen Sequence: EGT(pY)CCG(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues E366 to G372; in the region between the Transglut_core and Transglut_C domains. The effect of Y369 phosphorylation is unclear. This is the major in vivo phosphorylation site in TGM2 based on ≥618 mass spectrometry reports recorded in PhosphoSitePlus.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: TGM2 (Transglutaminase 2 or Tissue Transglutaminase) is a member of the transglutaminase family of enzymes that catalyzes the crosslinking of proteins and the conjugation of polyamines to proteins. It is a multifunctional, calcium-dependent enzyme that cross-links proteins, stabilizing the extracellular matrix (ECM) and remodeling the cytoskeleton. It exists in various cellular locations (cytoplasm, nucleus, extracellular space) and is involved in cell death, signalling, and adhesion. The protein acts as a monomer, is induced by retinoic acid, and appears to be involved in apoptosis. It switches between a "closed" (active GTP-binding) and "open" (active transamidase) conformation, acting as a molecular switch. TGM2 phosphorylates proteins such as p53. It features 4 domains (N-terminal beta-sandwich, catalytic core, two C-terminal beta-barrels). It is found in the cytosol, nucleus, associated with the mitochondria, and in the extracellular matrix.High expression of TGM2 is associated with cancer metastasis (breast, colon), and it acts as an autoantigen in dermatitis herpetiformisThis description may include information annotated by UniProt and/or Google AI.
