Introduction of PAR3
PAR3, also known as coagulation factor II receptor-like 2 (F2RL2) or thrombin receptor-like 2, is a protein of 374 amino acids and has approximately 42.5 kDa molecular mass. In humans, it is encoded by the gene F2RL2 located at the chromosome 5q13.3. PAR3 belongs to the protease-activated receptor (PAR) family, a subfamily of seven transmembrane G protein-coupled receptor, and is activated by thrombin.

Function of PAR3 Membrane Protein
This protein functions as a cofactor involved in the thrombin-mediated cleavage and activation of the PAR family member proteinase-activated receptor (PAR4). This receptor coupled to G proteins stimulates thrombin-triggered phosphoinositide hydrolysis and is found in many different tissues. PAR3 protein products play an important role in hemostasis and thrombosis and alternate splicing of it can lead to multiple transcript variants encoding diverse isoforms.

Application of PAR3 Membrane Protein in Literature
This article aimed to discuss the diverse signaling mechanisms and effector functions which have been linked to PAR3, PAR6, together with aPKC during the establishment of neuronal polarity.
The data from authors indicated that Par3 and aPKCλ cooperate to facilitate skin tumor initiation and progression, likely via sustaining survival, growth, and inflammatory signaling.
This article revealed that Par3 can potentially recruit two Par6 proteins meanwhile, which may promote the assembly of polarity protein networks by the interaction of multivalent PDZ domain.
The results of this paper suggested that the down-expression of PKCζs is an independent poor prognostic and metastatic factor for the colorectal adenocarcinoma (CRAC).
The bioinformatic and biochemical evidence provided by the researchers showed that SIK has potential to phosphorylate the polarity complex protein of Par3, a well-established regulator of tight junction assembly.
