Protein

Protein chibby homolog 1

Gene

Cby1

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Inhibits the Wnt/Wingless pathway by binding to 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 (By similarity). Promotes adipocyte and cardiomyocyte differentiation.By similarity2 Publications

Tissue specificityi

Found in heart, brain, lung, liver, muscle, kidney and testis. Levels are approximately 3-fold higher in embryonic and adult heart than in lung or liver.1 Publication

Developmental stagei

Ubiquitously expressed in early stages of embryonic stem cell differentiation but decreases at later stages when high expression is restricted to cardiomyocytes.1 Publication
