Our findings identify a mechanism that YTHDF1-mediated translation of m6A-modified Robo3.1 mRNA controls pre-crossing axon guidance in spinal cord
Title: The m6A reader YTHDF1 regulates axon guidance through translational control of Robo3.1 expression.
This study show that this commissural neuron population includes spinal inhibitory neurons and sensory nociceptors and show that this population depends on Robo/Slit signaling yet crosses the dorsal midline in a Robo3-independent manner.
Title: Sensory and spinal inhibitory dorsal midline crossing is independent of Robo3.
These findings identify NELL2 as an axon guidance cue and establish Robo3 as a multifunctional regulator of pathfinding that simultaneously mediates NELL2 repulsion, inhibits Slit repulsion, and facilitates Netrin attraction to achieve a common guidance purpose.
Title: Operational redundancy in axon guidance through the multifunctional receptor Robo3 and its ligand NELL2.
results suggest that Robo3 evolution was key to sculpting the mammalian brain by converting a receptor for Slit repulsion into one that both silences Slit repulsion and potentiates Netrin attraction
Title: Signaling switch of the axon guidance receptor Robo3 during vertebrate evolution.
this study demonistrated that Robo3-driven axon midline crossing conditions functional maturation of a large commissural synapse.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
