This morning my ChatGPT quota was inexplicably exhausted.

It took a while but I pieced it together. Voice mode somehow got activated when I went to bed.

The bot then engaged in a 10 hour conversation with my snoring dog, answering questions the pup wasn’t asking and praising him for his insight.

FACT OF THE DAY. 2 September 1752. Britain replaced the Julian calendar with the Gregorian one which was used in most of Europe. The following day was 14 September 1752, meaning 11 days were cut from the 1752 British calendar. These days simply never existed.

Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪

How do cells keep their cilia “clean” and functional? Our new study uncovers a conserved mechanism for retrieving polyubiquitinated proteins from #cilia – a process essential for cellular signaling and health. #cellbiology #ciliopathy #ubiquitin #IFT 🧵👇 1/n
A conserved mechanism for the retrieval of polyubiquitinated proteins from cilia
The temporospatial distribution of proteins within cilia is regulated by intraflagellar transport (IFT), wherein molecular trains shuttle between the cell body and cilium. Defects in this process impair various signal-transduction pathways and cause ciliopathies. Although K63-linked ubiquitination appears to trigger protein export from cilia, the mechanisms coupling polyubiquitinated proteins to IFT remain unclear. Using a multidisciplinary approach, we demonstrate that a complex of CFAP36, a conserved ciliary protein of previously unknown function, and ARL3, a GTPase involved in ciliary import, binds polyubiquitinated proteins and links them to retrograde IFT trains. CFAP36 uses a coincidence detection mechanism to simultaneously bind two IFT subunits accessible only in retrograde trains. Depleting CFAP36 accumulates K63-linked ubiquitin in cilia and disrupts Hedgehog signaling, a pathway reliant on the retrieval of ubiquitinated receptors. These findings advance our understanding of ubiquitin-mediated protein transport and ciliary homeostasis, and demonstrate how structural changes in IFT trains achieve cargo selectivity. ### Competing Interest Statement The authors have declared no competing interest.
