Research AreasOthers

Function

In the vertebrate host, binds to highly sulfated heparan sulfate proteoglycans (HSPGs) on the surface of host hepatocytes and is required for sporozoite invasion of the host hepatocytes.

Biological Context

Subcellular Location: Cell membrane (Lipid-anchor, GPI-anchor); Cytoplasm

Product Specifications

Recombinant Plasmodium knowlesi Circumsporozoite protein is a recombinant protein from Plasmodium knowlesi (strain H), expressed in E.coli, covering amino acids 20-363aa, with N-terminal 10xHis-tagged and C-terminal Myc-tagged tag, molecular weight 42.2kDa, purity Greater than 90% as determined by SDS-PAGE..
