General annotation (Comments)

Function

Acts as a ligand for the KLRK1 receptor and mediates NK cell cytotoxicity via the receptor. Ref.1

Subunit structure

Binds to KLRK1/NKG2D. Also binds the CMV glycoprotein UL16. Ref.1

Subcellular location

Cell membrane; Single-pass type I membrane protein Ref.1.

Tissue specificity

Highly expressed in colon and in a number of tumor cell lines. Ref.1

Sequence similarities

Belongs to the MHC class I family.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 Ref.1 (identifier: Q6H3X3-1)

Also known as: RAET1G1;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 Ref.1 (identifier: Q6H3X3-2)

Also known as: RAET1G2;

The sequence of this isoform differs from the canonical sequence as follows:
     211-213: APP → GTV
     214-334: Missing.
