MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] PEAR1 is a platelet receptor that signals upon the formation of platelet-platelet contacts independent of platelet activation and secondary to platelet aggregation (Nanda et al., 2005 [PubMed 15851471]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Mice homozygous for a knock-out allele show no apparent defects in hemostasis or thrombus formation. Although in vitro dextran sulfate-induced platelet aggregation is impaired, platelet aggregation initiated with physiological agonists is normal. [provided by MGI curators]

Protein Function and Prediction

Platelet endothelial aggregation receptor 1 (Pear1) is a type 1 membrane protein of the multiple epidermal growth factor (EGF)-like domain family that signals upon the formation of platelet-platelet contact (1-3). During platelet aggregation, PEAR1 is phosphorylated and recruits p85 PI3K, subsequently leading to the persistant activation of PI3K and Akt and the amplification of αIIbβ3 activation (3). Amplification of αIIbβ3 activation results in the stabilization of platelet aggregates (3). Pear1 also function in apoptotic neuron clearance in the embryonic dorsal root ganglia via an engulfment-dependent activity (4). SNPs in PEAR1 are linked to increased or decreased platelet responses to various agonists (2;5-7).

Expression/Localization

Pear1 is most highly expressed in platelets and endothelial cells followed by megakaryocytes, osteoblasts, coronary smooth muscle cells, and erythroid cells (1). Pear1 is also expressed in satellite glial cell precursors (4). In human tissues, PEAR1 expression was detected in heart, kidney, skeletal muscle, pancreas, ovary, breast, lung, brain cortex, hypothalamus, spinal cord, and dorsal root ganglion; expression was not detected in liver, small intestine, and colon (1).
