-  Comments and Description Text from UniProtKB
  ID: CD244_HUMAN
DESCRIPTION: RecName: Full=Natural killer cell receptor 2B4; AltName: Full=NK cell activation-inducing ligand; Short=NAIL; AltName: Full=NK cell type I receptor protein 2B4; Short=NKR2B4; Short=h2B4; AltName: CD_antigen=CD244; Flags: Precursor;
FUNCTION: Modulate other receptor-ligand interactions to enhance leukocyte activation.
SUBUNIT: Interacts with CD48. Following phosphorylation, it is able to recruit PTPN11/SHP-2 and SH2D1A/SAP. Binding of SH2D1A/SAP to CD244 prevents its association with PTPN11/SHP-2.
INTERACTION: P09326:CD48; NbExp=2; IntAct=EBI-1580565, EBI-714770;
SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein (Potential).
TISSUE SPECIFICITY: Expressed in spleen, PBL, followed by lung, liver, testis and small intestine. Expressed not only in NK cells, but also on monocytes and basophils.
SIMILARITY: Contains 2 Ig-like (immunoglobulin-like) domains.

ModBase Predicted Comparative 3D Structure on Q9BZW8
FrontTopSide
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
