Catalog No. ABIN2180732

Product Details

Target: 2B4 (CD244) (Natural Killer Cell Receptor 2B4 (CD244))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 22-221

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: This 2B4 protein is labelled with Fc Tag.

Sequence: AA 22-221

Characteristics: This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 48.9 kDa. As a result of glycosylation, the protein migrates as 65-80 kDa under reducing (R) condition, and 130-160 kDa under non-reducing (NR) condition (SDS-PAGE).

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.
