CATEGORY

immunity/defense , receptor membrane

SUBCELLULAR LOCALIZATION	plasma membrane
text	type I membrane protein

basic FUNCTION	inhibiting the activity of NK cells thus preventing cell lysis
	as other KIR genes, suppressed by DNA methylation in most T cells, and DNA demethylation promotes their expression through effects on both chromatin structure and transcription factors (Liu 2009)
