Homeobox protein notochord (NOTO)

Transcription regulator acting downstream of both FOXA2 and Brachyury (T) during notochord development. Required for node morphogenesis.

Is crucial for cilia formation in the posterior notochord (PNC) and for left-right patterning; acts upstream of FOXJ1 and RFX3 in this process and is required for the expression of different components important for axonemal function and assembly. Plays a role in regulating axial versus paraxial cell fate (By similarity).
