Summary: Predicted to enable RNA polymerase II-specific DNA-binding transcription factor binding activity; cytoskeletal protein binding activity; and protein-macromolecule adaptor activity. Involved in several processes, including fat cell differentiation; negative regulation of appetite by leptin-mediated signaling pathway; and regulation of cilium beat frequency involved in ciliary motility. Acts upstream of or within several processes, including cilium assembly; nervous system development; and regulation of organelle organization. Located in several cellular components, including centriolar satellite; photoreceptor cell cilium; and photoreceptor inner segment. Part of BBSome. Is expressed in several structures, including brain; cardiovascular system; eye; genitourinary system; and gut. Used to study Bardet-Biedl syndrome 4 and obesity. Human ortholog(s) of this gene implicated in Bardet-Biedl syndrome 4; morbid obesity; and obesity. Orthologous to human BBS4 (Bardet-Biedl syndrome 4).

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.
