Encodes an active AGC VIII protein kinase that interacts with the putative transcription factor ATS and regulates planar growth during integument development in the ovule. Mutants exhibit ectopic growth in filaments and petals%2C as well as aberrant embryogenesis.
TPX2 (targeting protein for Xklp2) protein family%3B CONTAINS InterPro DOMAIN/s: Xklp2 targeting protein (InterPro:IPR009675)%3B BEST Arabidopsis thaliana protein match is: WVD2-like 1 (TAIR:AT3G04630.3)%3B Has 678 Blast hits to 638 proteins in 104 species: Archae - 2%3B Bacteria - 22%3B Metazoa - 209%3B Fungi - 27%3B Plants - 299%3B Viruses - 0%3B Other Eukaryotes - 119 (source: NCBI BLink).
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.
Major facilitator superfamily protein%3B CONTAINS InterPro DOMAIN/s: Major facilitator superfamily%2C general substrate transporter (InterPro:IPR016196)%2C Biopterin transport-related protein BT1 (InterPro:IPR004324)%3B BEST Arabidopsis thaliana protein match is: Major facilitator superfamily protein (TAIR:AT5G25050.1)%3B Has 1010 Blast hits to 995 proteins in 167 species: Archae - 4%3B Bacteria - 188%3B Metazoa - 0%3B Fungi - 6%3B Plants - 265%3B Viruses - 0%3B Other Eukaryotes - 547 (source: NCBI BLink).
Encodes protein similar to yeast SCP98. Yeast SCP98 is essential for the microtubule nucleation activity of the gamma-tubulin ring complexes. Enriched at the post-cytokinetic cell edges in leaves and roots.
Encodes a protein with beta-glucosidase and galactosyltransferase activity%2C mutants show increased sensitivity to freezing. Though it is classified as a family I glycosyl hydrolase%2C it has no hydrolase activity in vitro.
UGT72E1 is an UDPG:coniferyl alcohol glucosyltransferase which specifically glucosylates sinapyl- and coniferyl aldehydes. The enzyme is thought to be involved in lignin metabolism.
Component of the WAVE protein complex which act as activators of ARP2/3 complex involved in actin nucleation. Required for trichome morphogenesis. Mutant displays distorted trichomes%2C a phenotype that can be phenocopied by treatment of WT plants with actin-interacting drugs. Its ER localization is independent of upstream SPK1 activation signaling and the physical association with the WAVE/SCAR Regulatory complex binding partner SRA1. ER-localized NAP1 has little colocalization with actin and represent the inactive pool of NAP1 in these cell types.
Similar to ACD1. Leaves of antisense ACD1-like plants turn yellow in darkness like wild-type whereas antisense ACD1 plants remain dark after five days of dark treatment.
Encodes a protein with isochorismate synthase activity. Mutants fail to accumulate salicylic acid. Its function may be redundant with that of ICS2 (AT1G18870).
