Dr. Lingappa is well known for her studies demonstrating that host enzymes are co-opted by viruses for the purpose of facilitating capsid assembly. In 2002, her lab reported in the journal Nature that a cellular ATPase, ABCE1, plays a critical role in assembly of the HIV-1 viral capsid. More recently, her group demonstrated that the cellular factor DDX6, an RNA helicase, is critical for HIV-1 capsid assembly.

Clinical interests

Jaisri Lingappa’s lab studies how viruses hijack host proteins to promote assembly of human immunodeficiency virus type 1 (HIV-1) and other viruses, using biochemical and cell biological approaches. Our group has demonstrated that, in cells, the assembly of immature HIV-1 capsids occurs through a pathway of assembly intermediates, and is facilitated by the catalytic activity of the host enzymes ABCE1 and DDX6. To form assembly intermediates (also called “assembly machines”), HIV-1 co-opts sites of RNA metabolism called RNA granules.
