Egg cell-secreted protein (DUF1278);(source:Araport11)
TAIR Curator Summary
Encodes a small cysteine-rich protein that is secreted by the egg cell during gamete interactions. The regulated secretion of EC1 by the egg cell upon sperm-egg interaction is proposed to ensure the appropriate localization of the cell-fusion machinery in distinct sperm membrane domains to accomplish gamete fusion.
Involved in the regulation of gamete interactions during the double fertilization and to prevent multiple-pollen tube attraction; mediates the redistribution of the gamete fusogen HAP2/GCS1 to the cell surface after secretion upon sperm arrival.
