功能Probable pathogen-recognition receptor involved in peripheral immune surveillance in liver. May mediate the endocytosis of pathogens which are subsequently degraded in lysosomal compartments. Probably recognizes in a calcium-dependent manner high mannose N-linked oligosaccharides in a variety of pathogen antigens, including HIV-1 gp120, HIV-2 gp120, SIV gp120, ebolavirus glycoproteins, HCV E2, and human SARS coronavirus protein S. Is a receptor for ICAM3, probably by binding to mannose-like carbohydrates. Is presumably a coreceptor for the SARS coronavirus.
组织特异性Predominantly highly expressed in liver sinusoidal endothelial cells and in lymph node. Found in placental endothelium but not in macrophages. Expressed in type II alveolar cells and lung endothelial cells.
序列相似性Contains 1 C-type lectin domain.
结构域The tandem repeat domain, also called neck domain, mediates oligomerization.
Lane 1 – MW markers; Lane 2 – ab83920; Lane 3 – ab83920 treated with PNGase F to remove potential N-linked glycans. 10 μg protein loaded per lane. Deep Purple stained. Drop in MW after treatment with PNGase F indicates presence of N-linked glycans. Band in lane 3 at 35 kDa is PNGase F protein.
SDS-PAGE - CD299 -Fc Chimera (ab83920)
A sample of ab83920 without carrier protein was reduced and alkylated. 40 μg protein was loaded, focused on a 3-10 IPG strip then run on a 4-20% Tris-HCl 2D gel. Spot train (Deep Purple™ stained) indicates presence of multiple glycoforms of ab83920. Spots within the spot train were cut from the gel and identified by protein mass fingerprinting as CD299 (Fc Chimera).
Functional Studies - CD299 -Fc Chimera (ab83920)
Post-translational modifications result in protein heterogeneity. The densitometry scan demonstrates the purified human cell expressed protein exists in multiple glycoforms, which differ according to their level of post-translational modification. The triangle indicates theoretical pI and MW.
