Mechanism of activation of an ancestral Tec kinase by PIP3

Eva Krötenheerdt, Lucas Piëch, Freia von Raußendorf, Ronja Reinhardt, Ranjana Nataraj, Nicholas Wedige, Hunter G. Nyvall, Emma E. Walsh, John E. Burke, Thomas A. Leonard

This study identifies how PIP3 activates an ancestral Tec kinase by displacing its PH domain from an inhibitory interaction with its kinase domain.

Avian influenza virus neuraminidase stalk length and haemagglutinin glycosylation patterns reveal molecularly directed reassortment promoting the emergence of highly pathogenic clade 2.3.4.4b A (H5N1) viruses

Ranjana Nataraj, Anantika Chandra, Sannula Kesavardhana

This paper identifies molecular factors driving the emergence of highly pathogenic H5N1 influenza viruses by showing HA glycosylation and NA stalk length determine subtype pairing and viral fitness.
