Attractant signaling by an aspartate chemoreceptor dimer with a single cytoplasmic domain.

Science (New York, N.Y.) - 18 Oct 1996

Gardina P J, Manson M D

Abstract excerpt

Signal transduction across cell membranes often involves interactions among identical receptor subunits, but the contribution of individual subunits is not well understood. The chemoreceptors of enteric bacteria mediate attractant responses by interrupting a phosphotransfer circuit initiated at receptor complexes with the protein kinase CheA. The aspartate receptor (Tar) is a homodimer, and oligomerized...
