Post-translational modifications for PEAR1 Gene

  • Phosphorylated in the intracellular domain on tyrosine residues (By similarity). Phosphorylated on tyrosine residues by SRC. Tyrosine phosphorylation is detected upon platelet aggregation stimulated by collagen, TRAP and thrombin and platelet-platelet contacts but not after platelet activation. Tyrosine phosphorylation enhanced its association with SHC1 and SHC2.
  • Glycosylation at Asn152, Asn271, Asn476, Asn575, and Asn634
