Demonstration of an analogue to human pregnancy zone protein in the African green monkey

An animal model for the study of the function of pregnancy-specific beta 1-glycoprotein and pregnancy zone protein: a review

Two pregnancy-associated murine proteins, PAMP-1 and PAMP-2, have been found to be immunologically cross-reacting analogues to the human proteins pregnancy zone protein (PZP) and pregnancy-specific beta 1-glycoprotein (SP-1), respectively. In this study, the physiochemical and biological properties of the proteins are compared and the effect on pregnancy of administration of monospecific antibodies against the proteins is reported.

Comparison of pregnancy-associated murine protein-1 and human pregnancy zone protein

Immunological cross-reaction between human pregnancy zone protein (PZP, SP-3, alpha 2-PAG) and pregnancy-associated murine protein-1 (PAMP-1) was demonstrated by countercurrent line immunoelectrophoresis using antibodies against the proteins raised in hens. The levels of PZP and PAMP-1 were measured during pregnancy and found to be very similar in the first half of pregnancy. Both proteins were found to be heterogeneous and separable according to surface properties. It is suggested that the murine PAMP-1 can be used to study the physiology of human PZP.
