Summaries for F2R Gene

Entrez Gene Summary for F2R Gene

  • Coagulation factor II receptor is a 7-transmembrane receptor involved in the regulation of thrombotic response. Proteolytic cleavage leads to the activation of the receptor. F2R is a G-protein coupled receptor family member. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]

GeneCards Summary for F2R Gene

F2R (Coagulation Factor II Thrombin Receptor) is a Protein Coding gene. Diseases associated with F2R include Chromosome 5Q Deletion Syndrome and Leukocyte Adhesion Deficiency, Type Iii. Among its related pathways are GPCRs, Other and Apoptotic Pathways in Synovial Fibroblasts. Gene Ontology (GO) annotations related to this gene include G-protein coupled receptor activity and G-protein alpha-subunit binding. An important paralog of this gene is F2RL1.

UniProtKB/Swiss-Prot for F2R Gene

  • High affinity receptor for activated thrombin coupled to G proteins that stimulate phosphoinositide hydrolysis. May play a role in platelets activation and in vascular development.

Tocris Summary for F2R Gene

  • Protease-activated receptors (PARs, also known as thrombin receptors) are G-protein-coupled receptors, activated by cleavage of their N-terminal domains by serine proteases. Hydrolysis reveals a tethered peptide ligand, which affects transmembrane signaling.
