Research Backgrounds

Function:

GP-Ib, a surface membrane protein of platelets, participates in the formation of platelet plugs by binding to the A1 domain of vWF, which is already bound to the subendothelium.

PTMs:

Glycocalicin is the product of a proteolytic cleavage/shedding, catalyzed by ADAM17, which releases most of the extracellular domain. Binding sites for vWF and thrombin are in this part of the protein.

Subcellular Location:

Membrane>Single-pass type I membrane protein.

Fig. 4. Preparation and characterization of PM-sEVs. (A) Typical TEM images of sEVs and PM-sEVs. Both sEVs and PM-sEVs exhibited characteristic cup-shaped morphology. Scale bar = 100 nm. (B, C) Size distribution of sEVs and PM-sEVs by NTA analysis. sEVs and PM-sEVs exhibited similar size distributions. (D) Typical images of PM-sEVs, DiO-labeled sEVs, DiL-labeled PM. Scale bar = 20 μm. The co-localization (yellow signals) of DiO (sEVs) and DiL (PM) fluorescence indicates successful fusion. (E) Analysis of Tsg-101, Alix, CD9, GPIbα, Integrin β1 and Integrin α2 expression of sEVs, PM-sEVs and PM by WB. Note: (1) sEVs markers (Tsg101, Alix, CD9) were enriched in both sEVs and PM-sEVs. (2) PM markers (GPIbα, Integrin β1, Integrin α2) were expressed in PM and PM-sEVs, but absent (or very low) in sEVs, confirming the incorporation of PM proteins onto PM-sEVs. (F) Typical images of DiO-labeled sEVs and PM-sEVs incubated with HUVECs. Scale bar = 20 μm. The significantly enhanced cellular uptake of DiO-PM-sEVs compared to that of DiO-sEVs demonstrated the improved targeting efficiency mediated by the PM coating. (G) IVIS images showing the distribution of sEVs, PM-sEVs and PM in the spinal cord. The fluorescence intensity was higher at the SCI site in the PM-sEVs group than in the sEVs group. (H) Cur release kinetics. The sustained release kinetics of Cur from PM-sEVs-Cur and sEVs-Cur were compared to the faster release of Cur alone.
