Locus: AT5G18403
Chromosomal location: Chromosome 5 (nucleotide 6,114,963 to 6,116,032)
Protein: Uncharacterized DUF966 family protein (268 amino acids)
Expression: Limited public data; weakly expressed in roots and siliques based on Arabidopsis eFP Browser.
DUF966 domain: A conserved domain of unknown function, prevalent in plants.
Homologs: Found in Oryza sativa (rice) and Zea mays (maize), but functional studies are absent.
While no AT5G18403-specific antibody is documented, general principles for plant protein antibody development include:
| Parameter | Consideration | Relevance to AT5G18403 |
|---|---|---|
| Antigen Design | Requires known epitopes or structural data | Limited due to uncharacterized protein |
| Immunogen Synthesis | Recombinant protein or peptide fragments | Requires gene synthesis (no expression data) |
| Validation | Knockout mutants for specificity testing | No KO mutants reported for AT5G18403 |
| Applications | Western blot, immunofluorescence, IP-MS | Hypothetical without experimental confirmation |
Examples from the search results highlight methodologies that could apply to AT5G18403:
A. Recombinant Antibody Production ( ):
Phage display or hybridoma technology for monoclonal antibody generation.
Requires cloning AT5G18403 into expression vectors (e.g., E. coli, CHO cells).
Western blot: Compare wild-type vs. CRISPR-edited Arabidopsis lines.
Immunoprecipitation-MS: Identify interacting partners.
C. Commercial Antibody Standards ( ):
Polyclonal antibodies (e.g., ATG5 Antibody in ) use peptide immunogens (1-30 aa regions).
Storage: -20°C in aliquots to prevent freeze-thaw cycles.
Gene Characterization: Prioritize functional studies (e.g., knockout phenotyping, subcellular localization).
Antigen Design: Use in silico tools (e.g., I-TASSER, AlphaFold) to predict immunogenic regions.
Collaborative Efforts: Partner with repositories (e.g., Arabidopsis Biological Resource Center) for gene-specific reagents.
