Exploring cross-α amyloids: from functional roles to design innovations.

Amyloids are filamentous protein aggregates that have traditionally been associated with neurodegenerative diseases, although they are also known to play pivotal functional roles across diverse forms of life. Although the cross-β structure has represented the hallmark of amyloidal assemblies, a cross-α structure was recently characterized as a functional microbial amyloid, and further work has shown that de novo designed sequences also assemble into cross-α amyloids, emphasizing cross-α as an alternative paradigm for self-assembly into ordered aggregates. In this review, we summarize recent discoveries of cross-α amyloids both in nature and artificially designed systems, and we describe their fundamental structural organization, self-assembly mechanisms, and biological functions.
