General description

Adaptor protein-2 (AP2) is a key constituent of clathrin-coated vesicles that mediates the endocytosis of cell membrane components such as G protein-coupled receptors (GPCRs). AP2 is a heterotetramer that consists of α, β, μ and σ subunits which bind to tyrosine- and dileucine-based motifs on membrane-associated cargo proteins.
Monoclonal Anti-AP2 (mouse IgG1 isotype) is derived from the hybridoma A6/2/2 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a peptide corresponding to amino acids of human AP2α. In humans and mice, the adaptor protein-2 (AP2) family comprises five different transcription factors namely AP2α, AP2β, AP2 γ, AP2δ, and AP2ε. These proteins contain N-terminal transactivation domain and C-terminal helix-span-helix motif, which together with a central basic region facilitates dimerization and DNA binding.

Immunogen

peptide corresponding to amino acid 415-433 of human AP2α.

Application

Monoclonal Anti-AP2 antibody produced in mouse has been used in:
  • immunofluorescence staining
  • immunoblotting
  • immunohistochemistry

Biochem/physiol Actions

Adaptor protein-2 (AP2) expression is associated with the embryonic development. AP2β was found to be a tumor specific human telomerase reverse transcriptase (hTERT) promoter activator, suggesting it may be a biomarker for cancer diagnosis or as a cancer therapeutic target for inhibiting hTERT activity and tumor cell growth. In humans, mutations or loss of these genes result in increased tumor growth and metastasis. Specifically, AP2α loss causes down regulation of E-cadherin and matrix metallopeptidase 9 (MMP-9) activity, which in turn enhance tumorigenicity of colon cancer cells. This effect may also be the result of AP2α regulation by p53.

Physical form
