Super excited that this story by @borissieber.bsky.social is now on BioRxiv!

For decades, we thought there was no MAPK scaffold for the ERK-like cascade that promotes sexual reproduction in fission yeast ... until Boris found it !

See the thread 👇 and enjoy the paper!

Mammalian cells have KSR, budding yeast has Ste5… and fission yeast has Sms1 as the MAPK scaffold for sexual reproduction!

Very excited to share my postdoc work where we discover that the hemi-arrestin Sms1 binds all components of the MAPK cascade, including ERK-like Spk1

Schematic of MAPK signalling in fission yeast, budding yeast and Metazoa. No MAPK scaffold was known for ERK-like MAPK in fission yeast, as opposed to budding yeast Ste5 and metazoan KSR1/2.

Sex or growth? Life must continually balance these strategies. We forced yeast to choose and captured the trade-off in real time. Evolution rewired existing regulators and fixed them through genetic assimilation, creating specialists for sex at the cost of growth.
