“…21, № 4 its name changed to placental α2-microglobulin, α2-microglobulin of fertility (AMGF) and, finally, specific α2-microglobulin. Later glycodelin was characterized by several independent research groups as placental protein 14 (PP14) [9], pregnancyassociated endometrial α2-globulin (α2-PEG) [6], endometrial protein 15 (EP15) [7], progestagendependent endometrial protein (PEP) [21,23], alpha-2 uterine protein (AUP) [18,74], progesterone associated endometrial protein (PAEP) [29]. To avoid terminological confusion, Dell A. et al in 1995 [13] proposed a new protein's name: "glycodelin", reflecting its unique feature -sex-dependent glycosylation.…”
