EFR

Gene
EFR
Protein
LRR receptor-like serine/threonine-protein kinase EFR
Organism
Arabidopsis thaliana
Length
1031 amino acids
Function
Constitutes the pattern-recognition receptor (PPR) that determines the specific perception of elongation factor Tu (EF-Tu), a potent elicitor of the defense response to pathogen-associated molecular patterns (PAMPs). Reduces transformation by Rhizobium radiobacter probably by inducing plant defense during the interaction. Binding to the effector AvrPto1 from P.syringae blocks the downstream plant immune response while interaction with hopD2 decreases the phosphorylation level of EFR upon elf18 treatment. Specific endoplasmic reticulum quality control components (ERD2B, CRT3, UGGT and STT3A) are required for the biogenesis of EFR.
Similarity
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.

Gene
Efr
Protein
UDP-xylose and UDP-N-acetylglucosamine transporter
Organism
Drosophila melanogaster
Length
352 amino acids
Function
Sugar transporter that specifically mediates the transport of UDP-N-acetylglucosamine (UDP-GlcNAc), GDP-fucose and UDP-xylose. Functions redundantly with nac in the O-fucosylation of Notch, positively regulating Notch signaling. Involved in the biosynthesis of heparan sulfate-glycosaminoglycan (HS-GAG) and in Dpp signaling in the wing imaginal disk.
Similarity
Belongs to the nucleotide-sugar transporter family. SLC35B subfamily.
