VP8 — Zea mays

Summary

ZM00001EB153730 (VP8) on maize chromosome 3 encodes a glutamate carboxypeptidase II, also classified as an aminopeptidase NAALADL1 and a peptidase M28 family protein, with carboxypeptidase, metallocarboxypeptidase, aminopeptidase and metallopeptidase activities. The gene is associated with meristem cell maintenance, meristem development, endosperm development, seed maturation, regulation of seed maturation, regulation of developmental processes, cell differentiation, anthocyanin anabolism and proteolysis. It is linked to plant height. The encoded protein localises to the apical plasma membrane, endomembrane system and plasmalemma. Studies of related genes in other species, including glutamate carboxypeptidase 2 and transferrin receptor-like dimerisation domain-containing proteins, connect the family to similar peptidase functions.
