NMR Structure(hide GO term definitions)

Chain A (SRTX1_ATRIR | P0DJK0)

biological process
	GO:0050880	regulation of blood vessel size	Any process that modulates the size of blood vessels.
	GO:0019229	regulation of vasoconstriction	Any process that modulates the frequency, rate or extent of reductions in the diameter of blood vessels.
	GO:0042310	vasoconstriction	A decrease in the diameter of blood vessels, especially arteries, due to constriction of smooth muscle cells that line the vessels, and usually causing an increase in blood pressure.
cellular component
	GO:0005576	extracellular region	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
