GH3.10 Antibody

GHProtein Context

GH3.10 is part of the GH3 protein family, which conjugates auxins (e.g., indole-3-acetic acid, IAA) and jasmonates (JA) to amino acids, modulating their activity and bioavailability. In Arabidopsis thaliana, GH3.10 (AtGH3.10) is categorized under Group IB of the GH3 family . Unlike Group IA proteins (e.g., AtGH3.11/JAR1), which preferentially conjugate JA, AtGH3.10 shows no substrate preference for JA and is not implicated in JA signaling .

Key Functional Properties of GH3.10:

• Enzyme Activity: AtGH3.10 lacks detectable activity toward JA but may interact with other substrates .

• Biological Role: While its exact role remains unclear, GH3 proteins broadly regulate phytohormone levels, influencing growth and stress adaptation .

GHAntibody Development and Applications

Antibodies targeting GH3 proteins are typically monoclonal or polyclonal reagents used for:

• Western Blotting: Detecting protein expression in plant tissues.

• Immunocytochemistry: Localizing GH3.10 in cellular compartments.

• Enzyme Activity Studies: Validating substrate specificity via immunoprecipitation.

While no GH3.10-specific antibody is detailed in the provided sources, analogous GH3 antibodies (e.g., against AtGH3.5 or AtGH3.11) are employed to study enzymatic kinetics and tissue-specific expression .

Research Findings and Data

Studies on GH3 family proteins reveal substrate-specific conjugation activities. For example:

This table highlights AtGH3.10’s inactivity toward JA, distinguishing it from other GH3 members. Antibodies against such proteins enable functional studies, including knockout validation and activity assays.

Potential Challenges and Considerations

• Specificity: Cross-reactivity with other GH3 isoforms must be ruled out via epitope mapping or knockdown controls.

• Validation: Orthogonal methods (e.g., mass spectrometry) are essential to confirm antibody specificity .
