One for the Apicomplexa peeps:
ever wonder how does the IMC grow so fast during progeny formation? Where do all the lipids come from? In our latest work on malaria RBC stages we implicate this monster protein (~6000 residues!) and ER contact sites.
Happy+proud to share and keen to hear thoughts!

Conversion from a mutualist to a parasite (the polar extremes of symbiosis) created a new lineage of parasites (Apicomplexa) ~ 500 million years ago. Apicomplexa radiated with animals creating the modern parasites of humans such as malaria plus ~6,000 species of animal parasites.

Dual apical methyltransferases orchestrate motility initiation in apicomplexan parasites - Nature Communications
This study identifies the Apicomplexa-specific methyltransferase PCKMT and reveals how it works with the previously known AKMT in a two-step pathway that initiates parasite motility and invasion.

Excited to share our new paper!
Tepsin and AP4 mediate transport from the trans-Golgi to the plant-like vacuole in Toxoplasma gondii.

A great collaboration between the Meissner, Jiménez-Ruiz, and Dacks labs 🙌

New on bioRxiv!
Our manuscript shows how the methyltransferase PCKMT primes the conoid by retaining Formin1 for motility initiation in Toxoplasma gondii, working with AKMT to activate the parasite’s motility machinery.
