VP8 — Zea mays

Summary

ZM00001EB371150, designated VP8 (also known as PLA3) on maize chromosome 8, encodes a metallocarboxypeptidase with carboxypeptidase, aminopeptidase and metallopeptidase activities (EC 3.4.17.21). The protein contains a peptidase M28B domain and a PA domain. In maize, VP8 is associated with meristem cell maintenance, meristem development, endosperm development, seed maturation and its regulation, anthocyanin anabolism, proteolysis and cell differentiation. It localises to the apical plasma membrane, endomembrane system and plasmalemma. The gene has been linked to plant height and heading date. Studies of related genes in other species connect the VP8 family to days to heading.
