Transcriptional activator. Functions as a switch in neuronal development, participating in the differentiation of embryonic neuroectodermal cells into neural tissues by making the ectodermal cells responsive to FGF-neuralizing signals (By similarity). Downstream SRRT target that mediates the promotion of neural stem cell self-renewal (By similarity). The 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors.
