Format
Lyophilized
Reconstitution
Allow the vial and reconstitution buffer to equilibrate to room temperature. Briefly centrifuge or tap down the vial to ensure that all lyophilized powder is collected at the bottom of the vial. For the reconstitution of this product, we recommend adding PBS or sterile water to achieve a final antibody concentration of 1 mg/mL. Allow the vial to reconstitute for 10-15 minutes at room temperature with gentle agitation. Avoid vigorous shaking that can cause foaming and antibody denaturation. Aliquot into volumes based on your experiment and store liquid protein at -20°C or -80°C for long time.
Buffer
Lyophilized from sterile
Preservative
None
Storage
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Target

Full Name
Sialophorin
Function
Predominant cell surface sialoprotein of leukocytes which regulates multiple T-cell functions, including T-cell activation, proliferation, differentiation, trafficking and migration. Positively regulates T-cell trafficking to lymph-nodes via its association with ERM proteins (EZR, RDX and MSN) (By similarity).
Negatively regulates Th2 cell differentiation and predisposes the differentiation of T-cells towards a Th1 lineage commitment. Promotes the expression of IFN-gamma by T-cells during T-cell receptor (TCR) activation of naive cells and induces the expression of IFN-gamma by CD4+ T-cells and to a lesser extent by CD8+ T-cells (PubMed:18036228).
Plays a role in preparing T-cells for cytokine sensing and differentiation into effector cells by inducing the expression of cytokine receptors IFNGR and IL4R, promoting IFNGR and IL4R signaling and by mediating the clustering of IFNGR with TCR (PubMed:24328034).
Acts as a major E-selectin ligand responsible for Th17 cell rolling on activated vasculature and recruitment during inflammation. Mediates Th17 cells, but not Th1 cells, adhesion to E-selectin. Acts as a T-cell counter-receptor for SIGLEC1 (By similarity).
CD43 cytoplasmic tail
Protects cells from apoptotic signals, promoting cell survival.

Cellular Location
Membrane
Cell projection, microvillus
Cell projection, uropodium
Localizes to the uropodium and microvilli via its interaction with ERM proteins (EZR, RDX and MSN).
CD43 cytoplasmic tail
Nucleus
Nucleus, PML body
The sumoylated form localizes to the PML body.
Topology
Extracellular: 20-253
Helical: 254-276
Cytoplasmic: 277-400
PTM
Glycosylated; has a high content of sialic acid and O-linked carbohydrate structures.
Phosphorylation at Ser-355 is regulated by chemokines, requires its association with ERM proteins (EZR, RDX and MSN) and is essential for its function in the regulation of T-cell trafficking to lymph nodes.
Has a high content of sialic acid and O-linked carbohydrate structures.
Cleavage by CTSG releases its extracellular domain and triggers its intramembrane proteolysis by gamma-secretase releasing the CD43 cytoplasmic tail chain (CD43-ct) which translocates to the nucleus.
CD43 cytoplasmic tail
Sumoylated.
