Biotinylated Human 2B4 / CD244 / SLAMF4 Protein, Fc,Avitag™

Biotinylated Human 2B4 / CD244 / SLAMF4 Protein, Fc,Avitag™

• Background: Natural killer cell receptor 2B4 is also known as NK cell type I receptor protein 2B4 (NKR2B4 or h2B4), SLAM family member 4 (SLAMF4), Signaling lymphocytic activation molecule 4, CD antigen CD244. NKR2B4 / CD244 contains two Ig-like (immunoglobulin-like) domains. CD244 is expressed in spleen, PBL, followed by lung, liver, testis and small intestine. CD244 interacts with CD48. Following phosphorylation, CD244 is able to recruit PTPN11/SHP-2 and SH2D1A/SAP. SLAMF4 modulate other receptor-ligand interactions to enhance leukocyte activation. CD244/2B4 is the only heterophilic receptor of SLAM family.
• Description: Biotinylated Human 2B4, Fc,Avitag (2B4-H82F0) is expressed from human 293 cells (HEK293). It contains AA Cys 22 - Arg 221 (Accession # Q9BZW8-2).
• Specifications: This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 50.7 kDa. The protein migrates as 65-80 kDa under reducing (R) condition, and 130-160 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
