This gene encodes a member of the protease-activated receptor (PAR) family which is a subfamily of the seven transmembrane G protein-coupled cell surface receptor family. The encoded protein acts as a cofactor in the thrombin-mediated cleavage and activation of the protease-activated receptor family member PAR4. The encoded protein plays an essential role in hemostasis and thrombosis. Alternate splicing results in multiple transcript variants that encode different isoforms. [provided by RefSeq, Feb 2012]
Forensic Context
A study in rhesus macaques identified the F2RL2 as a shared upregulated differentially expressed gene between HCM-affected animals and pediatric/adult human hypertrophic cardiomyopathy [Rivas et al. DOI:10.1038/s41598-024-82770-4]. In a separate study using a rat model of mild traumatic brain injury, the F2RL2 exhibited decreased expression in the first hour post-trauma, with a gradual increase thereafter, indicating a time-dependent response to brain injury [Colak et al. DOI:10.1016/j.injury.2012.01.021].
