CD299 Protein, Human, Recombinant is expressed in HEK293 mammalian cells. The predicted molecular weight is 37 kDa and the accession number is Q9H2X3-1.

CD299 is also known as DC-SIGNR and CLEC4M, is a type II integral membrane protein. DC-SIGNR exists as a homotetramer, and the tandem repeat domain, also called neck domain, mediates oligermerization. Multiple human DC-SIGN CD209 splice forms exist, generating both membrane-bound and soluble forms. DC-SIGNR is ragarded as a pathogen-recognition receptor involved in peripheral immune surveillance in liver, and probably mediate the endocytosis of pathogens which are subsequently degraded in lysosomal compartments. DC-SIGNR appears to selectively recognize and bind many viral surface glycoproteins containing high mannose N-linked oligosaccharides in a calcium-dependent manner, including HIV-1 gp12, HIV-2 gp12, SIV gp12, ebolavirus glycoproteins, HCV E2, and human SARS coronavirus protein S, as well as the cellular adhesion protein ICAM3. DC-SIGN CD209 is expressed on dendritic cells (DC) and inflammatory macrophages and contributes to antigen presentation.

CD299 Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with hFc tag. The predicted molecular weight is 65 kDa and the accession number is Q9H2X3-1.
