FAMILY

G-protein coupled receptor 1 family

CATEGORY

receptor membrane G

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm

basic FUNCTION	involved in the regulation of the inflammatory system
	predominantly responding to ATP, involved in the regulation of cardiac muscle contraction
	major neutrophil chemotactic factor released from the intraluminal thrombus of abdominal aortic aneurysms (Houard 2009)
	G-protein-coupled receptors for leukotriene B4 functioning in host defense, inflammation, and immunity (Kuniyeda 2007)
	in granulocytes transducing intracellular signals through the Gi- and G16-classes of G proteins, which inhibit cAMP production and raise the intracellular calcium concentration (Hikiji 2009)

Marker
Therapy target	inhibition of LTB4R functions may represent a strategy for preventing bone resorption diseases (potential therapeutic target for bone resorption diseases) (Hikiji 2009)

ANIMAL & CELL MODELS

osteoclasts from Blt1-deficient mice showed reduced calcium resorption activities compared with wild-type osteoclasts (Hikiji 2009)
