At5g37040 Antibody

Definition and Target Specificity

The At5g37040 antibody is a polyclonal antibody raised against the protein product of the AT5G37040 gene in Arabidopsis thaliana. This gene encodes an F-box family protein, a component of the SCF (SKP1-Cullin-F-box) E3 ubiquitin ligase complex involved in protein ubiquitination and degradation . The antibody binds specifically to the target protein, enabling detection and functional analysis in experimental settings .

Biological Context of AT5G37040

The AT5G37040 gene is part of the F-box protein superfamily, which regulates diverse cellular processes such as:

• Protein turnover: Mediating substrate recognition for ubiquitination .

• Stress responses: Modulating abiotic/biotic stress signaling pathways.

• Developmental regulation: Influencing growth and flowering time.

F-box proteins typically interact with SKP1-like adaptors, forming SCF complexes that mark substrates for proteasomal degradation. While direct functional studies of AT5G37040 remain limited, its structural homology to characterized F-box proteins suggests roles in phytohormone signaling (e.g., auxin or jasmonate pathways) .
