Target Background

Function
KIN13A antibody targets an internal motor kinesin protein that is involved in trichome morphogenesis. This protein plays a key role in regulating the formation of Golgi-associated vesicles. Furthermore, it plays a central role in microtubule disassembly through the active ARAC10-ICR5 cascade, which ultimately establishes the secondary cell wall pattern in metaxylem vessel cells. KIN13A works redundantly with KIN13B to modulate cell wall synthesis and cell expansion through the THE1 pathway.
Gene References Into Functions
  1. Kinesin-13A plays a central role in microtubule disassembly via the active ROP-MIDD1 cascade, which establishes the secondary cell wall pattern in metaxylem vessel cells. PMID: 24280391
  2. Research has shown that RIP3 is localized at microtubules and interacts with the kinesin-13 family member AtKinesin-13A, suggesting a role for RIP3 in microtubule reorganization and a potential function in ROP-regulated polar growth. PMID: 20832900
  3. AtKinesin-13A decorates Golgi-associated vesicles and may be involved in regulating the formation of Golgi vesicles in the root-cap peripheral cells. PMID: 19939242

Q&A

Kinesin-13A (KIN13A) antibodies are critical tools for studying microtubule dynamics and cellular transport mechanisms. Below are structured FAQs addressing key research challenges and methodologies, informed by experimental approaches from recent studies.

Advanced Research Challenges

Resolving contradictions in KIN13A localization data across studies

Conflict SourceResolution Strategy
Cell cycle-dependent expressionSynchronize cell populations using double thymidine block
Post-translational modificationsCombine Phos-tag™ gels with mass spectrometry
Antibody lot variabilityBatch-test using standardized lysate panels

Designing assays to study KIN13A-actin interplay

  • Dual-channel TIRF microscopy: Simultaneously track KIN13A (antibody-labeled) and LifeAct-tagged actin filaments

  • Functional interference: Combine antibody-based inhibition with actin-disrupting drugs (latrunculin A/cytochalasin D)

  • Data normalization: Use kymograph analysis to account for cytoskeletal remodeling rates

Methodological Considerations

Integrating KIN13A antibody data with omics datasets

  • Cross-platform validation:

    • Correlate antibody-based protein levels with RNA-seq data

    • Perform cluster analysis of co-regulated genes (STRING DB)

    • Validate using CRISPRi knockdown + rescue experiments

Technical Troubleshooting

Addressing non-specific bands in Western blots

  • Stepwise refinement:

    • Pre-clear lysates with protein A/G beads

    • Use TGX™ gels for improved separation of 80-100 kDa proteins

    • Compare signal intensity in +/- crosslinker (DSP)-treated samples
