3.A.10.1.16
Vacuolar H+-pyrophosphatase of 771 aas, Ovp1.  Expression increases cold tolerance in rice (Zhang et al. 2011).  Rice also have a similar paralogue, Ovp2, of 767 aas (P93410).  It is 88% identical to Ovp1.  The corn (Zea mays) orthologue of 766 aas and 16 TMSs (97% identical to the rice protein), Vpp1, is up-regulated in shoots and roots of maize seedlings under dehydration, cold and high salt stresses, suggesting a role in abiotic stress tolerance (Yue et al. 2008).

Protein Name:Ovp1
Length:771
Molecular Weight:80636.00
Species:Oryza sativa (Rice) [4530]
