General annotation (Comments)

Function

Cytotoxicity-activating receptor that contributes to the increased efficiency of activated natural killer (NK) cells to mediate tumor cell lysis. Engagement of NCR3 by BAG6 also promotes dendritic cell (DC) maturation, both through killing those DCs that did not properly acquire a mature phenotype, and inducing NK cells to release TNFA and IFNG, which promotes DC maturation. Ref.1 Ref.10 Ref.13

Subunit structure

Homodimer in the unliganted form. Interacts with CD3Z. Interacts with and is activated by binding to B7H6. Interacts with and is activated by binding to BAG6. Ref.1 Ref.2 Ref.11 Ref.13 Ref.14 Ref.15 Ref.16

Subcellular location

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

Tissue specificity

Selectively expressed by all resting and activated NK cells and weakly expressed in spleen. Ref.1 Ref.2

Polymorphism

A genetic variation in NCR3 is associated with mild malaria susceptibility [MIM:609148].

Sequence similarities

Belongs to the natural cytotoxicity receptor (NCR) family.

Contains 1 Ig-like (immunoglobulin-like) domain.
