General description

Beta-catenin-interacting protein 1 (UniProt Q9NSA3; also known as Beta-catenin-interacting protein ICAT, Inhibitor of beta-catenin and Tcf-4) is encoded by the CTNNBIP1 (also known as ICAT) gene (Gene ID 56998) in human. Inhibitor of beta-catenin and TCF (ICAT) negatively regulates T-cell factor/lymphoid enhancer factor (TCF/LEF)–beta-catenin transcriptional activity by competing against TCF/LEF for beta-catenin binding. ICAT gene knockout leads to premature death of newborn mice with gut, kidney, and craniofacial anomalies, implicating an important role of ICAT in epithelial establishment/maintenance and neural crest cell differentiation. The motility of melanoma cells through 3D matrices in vitro relies on two interconvertible modes of movements. ICAT is reported to suppress the expression of developmentally downregulated 9 (NEDD9) of Wnt/beta-catenin signaling pathway in human Lu1205 melanoma cells, resulting in a shift from the Rac-dependent mesenchymal movement to the Rho/ROCK-dependent amoeboid motility in vitro and enhanced colonization of transplanted Lu1205 in the lungs of nude mice in vivo.

Characterization of Estrogen Receptor α Phosphorylation Sites in Breast Cancer Tissue Using the SNAP i.d® 2.0 System

A major focus of breast cancer research is to understand the mechanisms responsible for disease progression and drug resistance. Toward that end, it has been found that approximately two thirds of all human breast carcinomas overexpress the Estrogen Receptor α (ERα) protein and it remains the primary pharmacological target for endocrine therapy1,2. The normal cellular function of ERα is as a transcription factor that mediates a wide variety of physiological processes, many of which are dependent upon phosphorylation of the receptor at specific amino acid residues3,4. Indeed, ERα is known to be phosphorylated at a multitude of different sites, yet how these all correlate to disease remains unclear5. Here, we interrogated multiple sites of ERα for phosphorylation status by screening an extensive panel of different breast cancer patient samples and other non-breast cancer tissue microarray (TMA) slide samples to determine their relevance to disease.
