Thanks Omaya! I didn't test them in other species, but I did look at their similarity to the aligned myosin 2 of 'closer' relatives like Naegleria fowleri. Here's the N. gruberi (Ng) peptide sequences we used vs those of N. fowleri (Nf). I highlighted the identical residues in green.

Just for fun, here's a game I like to call "Find the neuron" with examples of olfactory sensory neuron images from Šmít et al 2017 (doi.org/10.7554/eLif...) and Filoreta ramosa, a free-living syncytial amoeba from a salt marsh.

My PhD work is up on bioRxiv! Read all about the #actin and #microtubule #cytoskeleton of the Rhizarian #amoeba Filoreta ramosa here: www.biorxiv.org/content/10.1...

A quick craft project: hand-cut phase annuli from construction paper to fit an "adopted" microscope that was missing ph1 ph2 and ph3

Acanthocystis (maybe?) from the same bog sample. Sometimes amoebae don't need phase contrast, especially if they're full of zoochlorellae/plastids! #protistsonsky #bogblog

A lucky find- Lesquereusia in the middle of division! When finished, it will fill the second test (shell) that it built. Local bog sample. #testateamoebae #protistsonsky

It's so beautiful! Is that what this one is?

It's not always amoebae and protists, I paint plants too #nepenthes #SciArt

More #SciArt watercolor doodles of #amoeba with filopodia and reticulopodia

On days like today, a little #SciArt goes a long way.
