Through its selective up‐regulation and strategic binding—in part overlapping with the binding sites of OLIG2, a key motor neuron differentiation activator—TAF9B contributes to the establishment and maintenance of a cell-type specific transcriptional program.

Although knockout studies revealed that loss of CINAP does not affect learning and memory, it does lead to increased locomotor and exploratory behaviors in mice. This finding underscores the nuanced nature of transcriptional regulation in the nervous system and suggests that factors like TTTY20, if involved, might also participate in fine-tuning neural gene expression and behavior. While the exact function of TTTY20 remains to be elucidated, the studies discussed here provide a broader framework for understanding how accessory proteins and alternative transcription complexes modulate neuronal identity and activity."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Francisco J Herrera, Teppei Yamaguchi, Henk Roelink, et al.
