Glycerophosphoinositol inositolphosphodiesterase GDPD2 (GDPD2)

Has glycerophosphoinositol inositolphosphodiesterase activity and specifically hydrolyzes glycerophosphoinositol, with no activity for other substrates such as glycerophosphoinositol 4- phosphate, glycerophosphocholine, glycerophosphoethanolamine, and glycerophosphoserine. Accelerates the program of osteoblast differentiation and expansion.

May play a role in remodeling of the actin cytoskeleton (By similarity). .
