Robo1 Gene Summary [Rat]
Enables axon guidance receptor activity. Involved in several processes, including cellular response to hypoxia; negative regulation of synapse assembly; and nervous system development. Located in axon; dendrite; and neuronal cell body. Biomarker of diabetic retinopathy; lung non-small cell carcinoma; and transient cerebral ischemia. Human ortholog(s) of this gene implicated in autosomal recessive congenital nystagmus; combined or isolated pituitary hormone deficiency 8; congenital nystagmus; multiple myeloma; and plasmacytoma. Orthologous to human ROBO1 (roundabout guidance receptor 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Robo1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
