General description

Cateninβ is a multifunctional protein, coded by CTNNB1 (cateninβ 1) gene. It is present in the intracellular side of the cytoplasmic membrane. It is located on human chromosome 3p22.1.


synthetic phosphopeptide corresponding to the region that contains serine 33 of human β-catenin.


Monoclonal Anti-phospho-β-Catenin (pSer33) antibody produced in mouse is suitable for microarray and western blotting at a concentration of 5μg/mL using total cell extracts of cultured HEK-293T cells treated with MG132.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.

Biochem/physiol Actions

Catenin (cadherin-associated protein), β 1 (88kDa) protein is encoded by CTNNB1 gene in humans. It is also called as β-catenin. It is a dual function protein that regulates the coordination of cell-cell adhesion and gene transcription. Human β-catenin is located at band p21 on chromosome 3.

Mutations in β-catenin results in retinal vascular condition FEVR (familial exudative vitreoretinopathy). It participates in stimulating disease progression, providing BCR–ABL (fusion gene) kinase-independent resistance and LSC (leukemic stem cell) self-renewal. CTNNB1 plays an important role in cell-to-cell adhesion and transcriptional modulation in the Wnt signalling pathway.
