| 1349356 | ARL13B | ARF like GTPase 13B | This gene encodes a member of the ADP-ribosylation factor-like family. The encoded protein is a small GTPase that contains both N-terminal and C-terminal guanine nucleotide-binding motifs. This protein is localized in the cilia and plays a role in cilia formation and in maintenance of cilia. Mutatio ns in this gene are the cause of Joubert syndrome 8. Alternate splicing results in multiple transcript variants.

| 1557633 | Arl13b | ADP-ribosylation factor-like 13B | 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; cilia ry 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).
