Protein: Protein VACUOLELESS GAMETOPHYTES (Q6NQN8)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Essential for development of both female (megagametogenesis) and male (microgametogenesis) gametophytes by promoting the formation of large vacuoles early in development, maybe via the regulation of vesicular fusion.
Subcellular location: Endomembrane system {ECO:0000269|PubMed:28107777}. Prevacuolar compartment {ECO:0000269|PubMed:28107777}. Endosome, multivesicular body {ECO:0000269|PubMed:28107777}. Note=Localized to multivesicular bodies in gametophytes during mega- and microgametogenesis. {ECO:0000269|PubMed:28107777}.
