However, only a few Lokiarchaeum cells form these microtubules. And, unlike actin, these tubulin proteins only appear in very few species of Asgard archaea.

Its structure resembles HAP2. Archaea can be tough or impossible to grow in the lab with current techniques. But when archaeal Fsx1 was expressed in another type of cell, it prompted cell fusion.

He produced the tubulins in a cell culture with insect cells and examined their structure. ... Xu J, et al. Microtubules in Asgard archaea, Cell, published online March 21 2025, DOI 10.1016/j.cell ...

Two life forms living together helped spark the evolution of all complex life. By learning to appreciate this process more fully, we might be able to harness it to heal our planet too ...

Carl Woese, the influential American microbiologist who discovered archaea in the late 1970s, held that the three groups stood on their own, each alike in dignity, representing distinct “domains” of ...

This is only the second time Asgard Archaea cells have been grown and studied in detail. They specifically want to look at the DNA of these cells to see how similar they are to other groups and ...
