csgA expression entrains Myxococcus xanthus development. [PDF]
Genes & Development, 1992 The development cycle of the myxobacterium Myxococcus xanthus consists of three partially overlapping morphological stages referred to as rippling, fruiting body formation, and sporulation, all of which are absent in csgA null mutants. The CsgA gene product is an extracellular protein, referred to as the C signal, which is essential for developmental ...

CsgA-VHHs can neutralize S. flexneri contact-mediated hemolysis.
, 2022 PBP8 expressing CsgA-αIpaD-2, but not CsgA-αIpaD-1, inhibited hemolysis of sheep red blood cells, significantly outperforming the off-target negative control (CsgA-αGFP). Data presented as mean ± SEM.

CsgA-VHHs can bind soluble proteins.
, 2022 (a) GFP pull-down assay. After incubation with 150 nM GFP, PBP8 CsgA-αGFP bound specifically to its target, as demonstrated by the depletion GFP in the cell supernatant. (b) Stx2 pull-down assay.

CsgA-VHHs can bind to the eukaryotic pathogen Cryptosporidium parvum.
, 2022 (a) ELISA demonstrating the ability of CsgA-αgp900-2 to bind gp900. PBP8 was adsorbed onto a well plate, followed by incubation with gp900-containing C. parvum lysate. In the positive control, no PBP8 was used, and the C.

Variability of Amyloid Propensity in Imperfect Repeats of CsgA Protein of Salmonella enterica and Escherichia coli [PDF]
International Journal of Molecular Sciences, 2021 CsgA is an aggregating protein from bacterial biofilms, representing a class of functional amyloids. Its amyloid propensity is defined by five fragments (R1–R5) of the sequence, representing non-perfect repeats. Gate-keeper amino acid residues, specific to each fragment, define the fragment’s propensity for self-aggregation and aggregating ...
