== Function Summary ==
* **Entrez Summary**: This gene belongs to the G-protein-coupled receptor superfamily. The encoded integral membrane protein is a likely cannabinoid receptor. It may be involved in several physiological and pathological processes by activating a variety of signal transduction pathways. [provided by RefSeq, Aug 2013].
* **UniProt Summary**: May be involved in hyperalgesia associated with inflammatory and neuropathic pain (By similarity). Receptor for L- alpha-lysophosphatidylinositol (LPI). LPI induces Ca(2+) release from intracellular stores via the heterotrimeric G protein GNA13 and RHOA. Putative cannabinoid receptor. May play a role in bone physiology by regulating osteoclast number and function. {ECO:0000250, ECO:0000269|PubMed:19805329}.
