|Other Names||Protein chibby homolog 1, ARPP-binding protein, Cytosolic leucine-rich protein, PIGEA-14, PKD2 interactor, Golgi and endoplasmic reticulum-associated 1, CBY1, ARB1, C22orf2, CBY, PGEA1|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP9148b was selected from the C-term region of human HRIHFB2025. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Synonyms||ARB1, C22orf2, CBY, PGEA1|
|Function||Inhibits the Wnt/Wingless pathway by binding to CTNNB1/beta-catenin and inhibiting beta-catenin-mediated transcriptional activation through competition with TCF/LEF transcription factors. Has also been shown to play a role in regulating the intracellular trafficking of polycystin-2/PKD2 and possibly of other intracellular proteins. Promotes adipocyte and cardiomyocyte differentiation.|
|Cellular Location||Nucleus speckle. Golgi apparatus, trans-Golgi network. Note=Nuclear, in a punctate manner. Also found in the trans-Golgi|
|Tissue Location||Widely expressed. Expressed at higher levels in heart, skeletal muscle, kidney and placenta. Also found in brain, lung, liver and testis. Significantly down-regulated in thyroid and metastatic uterine tumors|
