BBS4 Is Essential for Nuclear Transport of Transcription Factors Mediating Neuronal ER Stress Response.
Horwitz A, Birk R. Horwitz A, et al. Mol Neurobiol. 2021 Jan;58(1):78-91. doi: 10.1007/s12035-020-02104-z. Epub 2020 Sep 7. Mol Neurobiol. 2021. PMID: 32894499
Hence, BBS4 is essential for nuclear transport under ER-stress response in neuronal cells during early differentiation. Our studies shed light on molecular mechanisms through which BBS4 malfunction alters neuronal ER stress response....

BBS4 protein has basal body/ciliary localization in sensory organs but extra-ciliary localization in oligodendrocytes during human development.
Bénardais K, Delfino G, Samama B, Devys D, Antal MC, Ghandour MS, Boehm N. Bénardais K, et al. Cell Tissue Res. 2021 Jul;385(1):37-48. doi: 10.1007/s00441-021-03440-9. Epub 2021 Apr 16. Cell Tissue Res. 2021. PMID: 33860840
We observed a correlation between the differentiation of the neurosensory cells (hair cells, photoreceptors, olfactory neurons) and the presence of a punctate BBS4 immunostaining in their apical cytoplasm. In the brain, BBS4 was localized in oligodendrocytes and mye …

BBS4 is required for intraflagellar transport coordination and basal body number in mammalian olfactory cilia.
Uytingco CR, Williams CL, Xie C, Shively DT, Green WW, Ukhanov K, Zhang L, Nishimura DY, Sheffield VC, Martens JR. Uytingco CR, et al. J Cell Sci. 2019 Feb 15;132(5):jcs222331. doi: 10.1242/jcs.222331. J Cell Sci. 2019. PMID: 30665891 Free PMC article.
Here, we report that Bbs4(-/-) mice exhibit shorter and fewer olfactory sensory neuron (OSN) cilia despite retaining odorant receptor localization. Within Bbs4(-/-) OSN cilia, we observed asynchronous rates of IFT-A/B particle movements, indicating miscoordination i …

Insulin regulates Bbs4 during adipogenesis.
Nahum N, Forti E, Aksanov O, Birk R. Nahum N, et al. IUBMB Life. 2017 Jul;69(7):489-499. doi: 10.1002/iub.1626. Epub 2017 Apr 3. IUBMB Life. 2017. PMID: 28371235 Free article.
Silencing of Bbs4 expression in adipocytes significantly impaired and reduced glucose uptake. This effect was reversed by Bbs4 overexpression. Inhibition of PI 3-kinase resulted in upregulation of Bbs transcripts, suggesting that the PI3K pathway is involved in the …
