Functional epitopes for site 1 of human prolactin.

Biochemistry - 1 Mar 2011

Rao Geeta Vittal, Brooks Charles L

Abstract excerpt

Human prolactin (hPRL) binds two human prolactin receptor molecules, creating active heterotrimeric complexes. Receptors bind dissimilar hormone surfaces termed site 1 and site 2 in an obligate ordered process. We sought to map the functional epitopes in site 1 of hPRL. Extensive alanine mutagenesis (102 of the 199 residues) showed approximately 40% of these mutant hPRLs changed the ΔG for site 1 receptor...
