Protein attributes

Sequence length	374 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Receptor for activated thrombin coupled to G proteins that stimulate phosphoinositide hydrolysis. Ref.9
Subunit structure	Interacts with INSC/inscuteable and probably GPSM2. Ref.10
Subcellular location	Cell membrane; Multi-pass membrane protein.
Tissue specificity	Highest expression in the megakaryocytes of the bone marrow, lower in mature megakaryocytes, in platelets and in a variety of other tissues such as heart and gut. Ref.8
Post-translational modification	A proteolytic cleavage generates a new N-terminus that functions as a tethered ligand.
Sequence similarities	Belongs to the G-protein coupled receptor 1 family.
Sequence caution	The sequence CAD97628.1 differs from that shown. Reason: Frameshift at position 374.
