LA VIE, L'AMOUR, LA MORT & LES PROTÉINES

Une BD dessinée par le talentueux aloys lolo qui raconte le riche et surprenant monde des protéines: à quoi elles ressemblent, à quoi elles servent et les multiples rôles qu'elles entretiennent au sein de tout organisme vivant - les plantes, comme les insectes, les lichens et les humains. Les histoires qu'on y raconte sont tirées du blog Protein Spotlight, dont les articles, écrits par Vivienne Baillie Gerritsen, sont lus depuis plus de 20 ans par la communauté scientifique à travers le monde.

parution octobre 2023, éd. Antipodes

IN GOOD TIME

All about a protein (ZAR1) that keeps immature egg cells as healthy as possible: from the moment a baby girl is born to the monthly time they leave the ovaries ready to meet a sperm cell.

CLEARING THE CLAMOUR

Like our homes, cells need to keep things clean. Lysosomes are cellular organelles that clear away anything that cells do not want anymore. This is the story of a protein that triggers off the making of lysosomes when they are needed, including at the very beginning of the immune response.

ON ANTS, BANDICOOTS AND GILBERTIAN MIMICRY

The story of an ant, Myrmecia gulosa, commonly known as the giant bull ant, and the way - over time - it has acquired a protein able to mimic a hormone which belongs to its predators, who - once stung - are inflicted such a lasting pain that they will think twice before touching a giant bull ant again.

illustration by Arthur Rackham (1867-1939)

A SHREWD TWEAK

Ribosomes are like small factories whose task is to make proteins in cells. Though it was believed that, throughout the different kingdoms, ribosomes were all alike, it turns out that some differ slightly in their makeup and are found only in certain kinds of cell - presumably because they synthesize proteins particular to these cells. One such ribosome has been discovered in sperm cells, along with a protein known as large ribosomal subunit protein eL39-like*, or RPL39L.

THE SLIME INSIDE US

We carry around two square metres of mucus inside us! It lines the mucous membranes of our body, where it keeps things lubricated and healthy. There's lots of water in it (94%) and many molecules - among them glycoproteins that carry sialic acid. Why sialic acid? Because it helps to keep pathogens away, and it is an enzyme - a sialyltransferase - that puts it there.

IN THE BEGINNING

How does life begin? What gives the first nudge? Is there, for that matter, a primordial poke? How do the first cells of an embryo know that it is time to multiply and differentiate? There are specific kinds of protein that are directly involved in driving cells to their fate. Their name? The tetra-peptide repeat homeobox proteins.
