Cation transporter/ E1-E2 ATPase family protein;(source:Araport11)
TAIR Curator Summary:
Encodes a putative auto-regulated Ca2+-ATPase located in the plasma membrane involved in transporting Ca2+ outside developing pollen grains. This activity is important to support normal pollen development, particularly the progression to uninucleated microspores to bicellular pollen grains.
