FtsY

Membrane Assembly of the E coli SRP Receptor

FtsY binds to membranes by binding to phosphatidylethanolamine (PE) and to an unknown membrane portein

Efficiency!!

When a signal peptide on a newly synthesized protein exits from the ribosome it and the ribosome are bound by SRP (signal recognition particle) and targeted to the translocon (Sec61 complex) via an interaction with the SRP receptor(SRa, SRb).

Current Projects

Assembly and function of the translocation machinery including the SRP receptor, Sec61b and Sec61g.

Assembly of the E. coli SRP receptor (FtsY).

Analysis of targeting mechanisms of proteins with tail-anchors including Sec61 b and g, Vamp proteins, and the Bcl-2 family of proteins that regulate apoptosis.
