Pregnancy associated glycoprotein subtypes : PAG

Answer 2

• Aspartate proteinase family members, proteolytic enzymes
• Cell specific expression
• Unknown function

Question 3

Pregnancy associated glycoprotein subtypes : PAG

bPAG-1

Answer 3

• Genetically younger cells produce
• Only binucleatee cells produce
• After day 25 of pregnancy proteins cross basement membrane and show up in maternal
circulation
• Higher plasma concentration in crossed animals
