Mitogen-regulated protein (MRP/PLF; also called proliferin) is a member of the PRL-GH family expressed by the placenta in mid-gestation. This report describes an MRP/PLF receptor in uterine membrane preparations from pregnant mice. Peak receptor activity occurred at 11 days of gestation with a dissociation constant of 6 x 10(-10) M and maximal binding capacity of 86 fmole MRP/PLF/mg membrane protein. PRL, PL-I, and mannose-6-phosphate did not compete for binding, and GH competed weakly only at… CONTINUE READING
