Summary: Predicted to enable GTPase activator activity. Acts upstream of or within several processes, including heart looping; photoreceptor cell maintenance; and photoreceptor cell outer segment organization. Predicted to be located in cell projection and plasma membrane. Predicted to be active in cilium and periciliary membrane compartment. Is expressed in several structures, including fertilized egg; liver and biliary system; pleuroperitoneal region; sensory system; and trunk. Used to study retinitis pigmentosa 2. Human ortholog(s) of this gene implicated in retinitis pigmentosa and retinitis pigmentosa 2. Orthologous to human RP2 (RP2 activator of ARL3 GTPase).

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.
