(2011). The M protein of group A Streptococcus is a key virulence factor and a clinically relevant strain identification marker. Virulence: Vol. 2, No. 5, pp. 402-412.

The M protein coats group A streptococci (GAS) and acts as the primary antigen and determinant of type-specific immunity. M is essential for GAS virulence, providing antiphagocytic functions critical to survival in human tissues 2010-06-01 2018-06-15 Using streptococcal strains with defined mutations in the genes which encode surface proteins in combination with primary cultures of human skin and an in situ adherence assay which uses histological sections of human skin, we show that the M protein of S. pyogenes mediates the binding of the bacterium to keratinocytes, while a second streptococcal surface protein, protein F, directs the … Remove.

The GAS M protein is a critical virulence factor in the fight against GAS infection, and it has been a primary target for GAS vaccine development.

23 Aug 2016 The sequences of M proteins are antigenically variable, but have in common the tendency to form α-helical coiled coil structures.

2016).

M and M-like proteins are major virulence factors of the widespread and potentially deadly bacterial pathogen Streptococcus pyogenes. These proteins confer resistance against innate and adaptive immune responses by recruiting specific human proteins to the streptococcal surface. To fend off sickness, plasma cells release proteins called antibodies.
