HSPRO1 Antibody

Biological Role of HSPRO1

HSPRO1 interacts with AKIN-βγ, a subunit of the SNF1-related protein kinase (SnRK1) complex, and is upregulated during Pseudomonas syringae infection in plants. This interaction suggests a role in metabolic reprogramming and stress adaptation, potentially influencing pathogen defense mechanisms .

3.1. Typical Applications

3.2. Recommended Dilutions

Based on analogous antibodies (e.g., HSPB1, HSF1):

• WB: 1:500–1:2000

• IHC/IF: 1:50–1:200

3.3. Validation Methods

• Knockdown Validation: Use of shRNA to confirm target specificity, as demonstrated for Hax1 antibodies .

• Cross-Reactivity Checks: Include lysates from HSPRO1-knockout models or unrelated cell lines .

4.1. Stress Response Mechanisms

HSPRO1 is upregulated under biotic stress (e.g., bacterial pathogens), suggesting it may modulate SnRK1 activity to rewire metabolic pathways during stress .

5.1. Antibody Sources

• Host Species: Rabbit or mouse polyclonal/monoclonal antibodies are common for heat shock proteins .

• Antigen Design: Recombinant HSPRO1 fragments or synthetic peptides corresponding to conserved domains .

5.2. Challenges in Development

• Specificity: Risk of cross-reactivity with homologs (e.g., HSPRO2) due to sequence similarity .

• Validation: Requires rigorous testing across applications (WB, IP, IF) and species .

Future Directions

• Functional Studies: Elucidate HSPRO1’s role in human diseases (e.g., metabolic disorders, cancer) using targeted antibodies.

• Therapeutic Potential: Engineering HSPRO1 antibodies with enhanced effector functions (e.g., prolonged half-life via FcRn-binding modifications) .
