Apr 30, 2018 moonlighting or multitasking proteins refer to those proteins with two or more functions performed by a single polypeptide chain.
The list of multifunctional proteins frequently referred to as 'moonlighting proteins' or multitasking enzymes involved in metabolic pathways and bacterial pathogenesis is rapidly expanding. The online moonprot database includes around 400 proteins displaying such moonlighting functions and it is likely that many other moonlighting proteins.

The β-hemolytic group a streptococcus (gas) is a major pathogen that readily uses hemoglobin to satisfy its requirements for iron. The streptococcal hemoprotein receptor in gas plays a central role in heme utilization and binds fibronectin and laminin in vitro.
Out of all studied proteins, about 25% of the proteins of the database exhibited virulence activity as a corresponding moonlighting function. Based on this peculiar observation, they hypothesized that pathogens mainly employ those proteins as virulent factors which exhibit high structural conservation towards their host counterparts.

Characterization of a novel protein generally involves finding a function for a protein, but it does not necessarily include a search for all possible additional functions of a protein. Most moonlighting functions have been found by chance, and there is not currently a good method for predicting which proteins moonlight.

We demonstrate that secreted virulence factors and ribosomal proteins play a so far unacknowledged role as moonlighting proteins, which contribute to biofilm integrity. This stabilizing effect is mediated by an acidic ecm environment caused by the release of fermentation products like formate, lactate, and acetate.
Moonlighting proteins: novel virulence factors in bacterial infections is a complete examination of the ways in which proteins with more than one unique biological action are able to serve as virulence factors in different bacteria.
The additional function of a moonlighting protein may be attributed to its original active site or to novel sites (reviewed in huberts and van der klei, 2010;henderson and martin, 2011); however.
Overview moonlighting proteins: novel virulence factors in bacterial infections is a complete examination of the ways in which proteins with more than one unique biological action are able to serve as virulence factors in different bacteria.
Protein moonlighting through gene sharing differs from the use of a single gene to generate different proteins by alternative rna splicing, dna rearrangement, or post-translational processing. It is also different from multifunctionality of the protein, in which the protein has multiple domains, each serving a different function.
They found that the nsp1 protein from pandemic sars-cov-2 binds to both, 40s subunits and to 80s ribosomes.
What are moonlighting proteins?moonlighting proteins comprise a class of multifunctional proteins in which a single protein performs multiple physiologically relevant biochemical or biophysical functions that are not due to gene fusions, multiple rna splice variants, or pleiotropic effects [jeffery, 1999]. Classic examples include soluble enzymes that also bind to dna or rna to regulate.

Moonlighting proteins play a central role in many diseases, and the development of novel treatments would be aided by more information addressing current questions, for example, how some are targeted to multiple cellular locations and how a single function can be targeted by therapeutics without targeting a function not involved in disease. This article is part of the theme issue 'heat shock proteins as modulators and therapeutic targets of chronic disease: an integrated perspective'.

Moonlighting activities include adhesion and modulation of cell signalling processes. It is likely that only the tip of the bacterial moonlighting iceberg has been sighted and the next decade will bring with it many new discoveries of bacterial moonlighting proteins with a role in bacterial virulence.
