Summary: Enables opsin binding activity. Involved in regulation of organelle assembly; regulation of platelet-derived growth factor receptor-alpha signaling pathway; and spermatogenesis. Acts upstream of or within several processes, including morphogenesis of a polarized epithelium; plasma membrane bounded cell projection organization; and protein transport. Located in several cellular components, including ciliary base; microtubule cytoskeleton; and photoreceptor cell cilium. Part of intraciliary transport particle B. Is expressed in cranium. Orthologous to human IFT20 (intraflagellar transport 20). [provided by Alliance of Genome Resources, Jun 2025]

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.
