These findings revealed previously unknown functions, suggesting that the enzyme can: (1) move into and out of intercellular space, (2) traverse cell walls, and (3) act as a growth factor to promote cellular ...
Consequently, we can now employ new experimental approaches to define mechanisms that regulate the complex metabolic flux of inositol phosphate biosynthesis and delineate the role of an essential enzyme ...
