Annotation score:4 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>-Experimental evidence at transcript leveli <p>This indicates the type of evidence that supports the existence of the protein.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Receptor for L-alpha-lysophosphatidylinositol (LPI). LPI induces Ca2+ release from intracellular stores via the heterotrimeric G protein GNA13 and RHOA (By similarity). Putative cannabinoid receptor (By similarity). May play a role in bone physiology by regulating osteoclast number and function (By similarity). May be involved in hyperalgesia associated with inflammatory and neuropathic pain.By similarity1 Publication

Miscellaneous

The classification of this protein as a cannabinoid receptor remains a contentious issue due to conflicting pharmacological results.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
