Arl13b Gene Summary [Mouse]
Predicted to enable GTP binding activity and GTPase activity. Involved in nervous system development; non-motile cilium assembly; and smoothened signaling pathway. Acts upstream of or within dorsal/ventral pattern formation; heart looping; and left/right axis specification. Located in axoneme; ciliary membrane; and motile cilium. Is expressed in several structures, including chordamesoderm; embryo mesenchyme; gonad; neural ectoderm; and node. Human ortholog(s) of this gene implicated in Joubert syndrome 8. Orthologous to human ARL13B (ARF like GTPase 13B). [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 mouse Arl13b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
