Activity summary

Wnt1 also known as Int-1 is a member of the Wnt gene family and is known for its role in encoding a protein that is involved in signaling pathways inside the cell. This protein weighs approximately 41 kDa and is expressed in various tissues including the brain and lungs. It functions by binding to receptors on the cell surface activating intracellular signaling pathways that govern cellular processes like proliferation and differentiation.

Biological function summary

Wnt1 plays a significant role in embryonic development. It is an integral component of the Wnt signaling complex which regulates important aspects such as cell fate determination patterning during embryogenesis and organogenesis. The protein's activity ensures that cells behave in a coordinated manner allowing for proper tissue development and growth.

Pathways

Wnt1 is essential in the canonical Wnt/β-catenin signaling pathway. This pathway involves the stabilization and accumulation of β-catenin in the cytoplasm and its subsequent translocation into the nucleus where it influences gene transcription. It also plays a role in the non-canonical Wnt pathways such as the planar cell polarity pathway but its primary activity is within the canonical one. Proteins like Frizzled and Dishevelled are closely related through these pathways facilitating the transduction of signals initiated by Wnt1.

Associated diseases and disorders

Wnt1 has been linked to cancers including breast and colorectal cancer due to its role in regulating cell proliferation and survival. Dysregulation of Wnt1 signaling can lead to poor control over cell growth contributing to oncogenesis. Wnt1 is also associated with bone density disorders as it critically affects bone formation and remodeling. In these contexts proteins such as LRP5/6 and β-catenin interact with Wnt1 mediating its effects on disease progression.
