Function
Component of the intercentrosomal linker and a key regulator of mitotic centrosome separation (18086858). Required for Kupffer鈥檚 vesicle (KV) and cilia formation, and organ laterality. Ctnnb1/2 activity in dorsal forerunner cells is required for cilia formation by controlling the expression of a set of transcription factors (22535411). Interacts with TCF family members, activating Wnt target genes (15852005). Ciliary deconstruction initiates the formation of metastasising melanoma by promoting WNT/尾-catenin sig ling (30008323).
Model organism evidence
(#)Contributed equally BACKGROUND: CFAP57 is essential for the development and function of sperm flagella, as it is required for the assembly and stability of the inner dynein arm (IDA) that drive sperm motility.
