Molecular weight (DA)
197kD
Immunogen
Synthesized peptide derived from part region of human protein
Specificity
PAPP2 Polyclonal Antibody detects endogenous levels of protein.
Formulation
Liquid in PBS containing 50% glycerol, and 0.02% sodium azide.
Dilution rate
WB 1:500-2000 ELISA 1:5000-20000
Purification process (Immunogen)

Background
This gene encodes a member of the pappalysin family of metzincin metalloproteinases. The encoded protein cleaves insulin-like growth factor-binding protein 5 and is thought to be a local regulator of insulin-like growth factor (IGF) bioavailability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2010],
Function
catalytic activity:Cleavage of the 143-Ser-|-Lys-144 bond in insulin-like growth factor binding protein (IGFBP)-5.,cofactor:Binds 1 zinc ion per subunit.,function:Metalloproteinase which specifically cleaves IGFBP-5. Shows limited proteolysis toward IGFBP-3.,similarity:Belongs to the peptidase M43B family.,similarity:Contains 5 Sushi (CCP/SCR) domains.,subunit:Monomer.,tissue specificity:Expressed abundantly in placenta, and non-pregnant mammary gland with low expression in the kidney, fetal brain and pancreas.,
