Summary: Predicted to enable RNA polymerase II-specific DNA-binding transcription factor binding 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 blood vessel diameter maintenance; brain development; and cilium assembly. Located in several cellular components, including microvillus; motile cilium; and stereocilium. Part of BBSome. Is expressed in central nervous system; early embryo; and retina. Used to study Bardet-Biedl syndrome 2. Human ortholog(s) of this gene implicated in Bardet-Biedl syndrome; Bardet-Biedl syndrome 2; obesity; and retinitis pigmentosa 74. Orthologous to human BBS2 (Bardet-Biedl syndrome 2). [provided by Alliance of Genome Resources, Jan 2025]

Title: Correction of cilia structure and function alleviates multi-organ pathology in Bardet-Biedl syndrome mice.
Bbs1, Bbs2, and Bbs4 proteins (BBSome) are bona fide constituents of intraflagellar transport in olfactory sensory neurons.
Title: Direct evidence for BBSome-associated intraflagellar transport reveals distinct properties of native mammalian cilia.
Data implicate Bardet-Biedl syndrome genes in the regulation of vascular function and demonstrate that disrupting Bbs2 and Bbs6 genes affect differentially the vascular function.

Bardet-Biedl syndrome (BBS) proteins mediate LepR trafficking and that impaired LepR signaling underlies energy imbalance in BBS.
Title: Requirement of Bardet-Biedl syndrome proteins for leptin receptor signaling.
Although BBS proteins were not required for ciliogenesis, their loss caused structural defects in a fraction of cilia covering mouse airway epithelia in Bbs1, Bbs2, Bbs4, and Bbs6 mutant mice.

Title: Bardet-Biedl syndrome proteins are required for the localization of G protein-coupled receptors to primary cilia.
mice lacking Bbs2 gene expression have phenotypes associated with cilia dysfunction, including retinopathy, renal cysts, male infertility, and a deficit in olfaction
Title: Bbs2-null mice have neurosensory deficits, a defect in social dominance, and retinopathy associated with mislocalization of rhodopsin.

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.
