WNT5B is a gene that encodes a protein involved in the Wnt signaling pathway, which plays a crucial role in cell communication and development. This pathway is important for processes such as cell growth, differentiation, and tissue repair. The WNT5B protein is particularly significant in the development of various tissues, including the nervous system and the skeleton. Abnormalities in WNT5B expression have been linked to several diseases, including certain types of cancer and developmental disorders, highlighting its importance in maintaining normal cellular functions.
