Gene : EC1.3 A. thaliana

DB identifier  ? AT2G21750 Secondary Identifier  ? locus:2052556
Name  ? EGG CELL 1.3 Brief Description  Egg cell-secreted protein (DUF1278)
TAIR Computational Description  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.
TAIR Short Description  Protein of unknown function (DUF1278)
TAIR Aliases  EC1.3

Type Comment Proteins
EC13_ARATH developmental stage Confined to the egg cell before fertilization, but disappears upon gamete fusion. Also present in zygotes and early embryos.
EC13_ARATH function 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.
EC13_ARATH similarity Belongs to the plant egg cell-secreted peptide family.
EC13_ARATH subcellular location Secreted via vesicle exocytose upon sperm arrival, especially in the apical region of the degenerating synergid cell.
EC13_ARATH tissue specificity Restricted to female reproductive tissues, specifically accumulating in storage vesicles of the unfertilized egg cell.
