Description: Recombinant human CD33 protein with C-terminal human Fc and 6×His tag
Background:
Sialic-acid-binding immunoglobulin-like lectin (Siglec) that plays a role in mediating cell-cell interactions and in maintaining immune cells in a resting state. Preferentially recognizes and binds alpha-2,3- and more avidly alpha-2,6-linked sialic acid-bearing glycans. Upon engagement of ligands such as C1q or syalylated glycoproteins, two immunoreceptor tyrosine-based inhibitory motifs (ITIMs) located in CD33 cytoplasmic tail are phosphorylated by Src-like kinases such as LCK. These phosphorylations provide docking sites for the recruitment and activation of protein-tyrosine phosphatases PTPN6/SHP-1 and PTPN11/SHP-2. In turn, these phosphatases regulate downstream pathways through dephosphorylation of signaling molecules. One of the repressive effect of CD33 on monocyte activation requires phosphoinositide 3-kinase/PI3K.
Synonyms: CD33,SIGLEC3,gp67
Molecular Weight: The protein has a predicted molecular mass of 53.8 kDa after removal of the signal peptide.
Purity: The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.
Buffer: PBS, pH7.4
Buffer: Store at -80°C for 12 months (Avoid repeated freezing and thawing)
Usage: Research use only
