CYCD3-3 Antibody

What is Cyclin D3 and why is it important in cell cycle research?

Cyclin D3 functions as a key regulator of Cyclin-dependent kinases 4 and 6 (CDK4 and CDK6), mediating growth factor-induced progression through the G1 phase in the cell cycle. As a regulatory component of the cyclin D3-CDK4 complex, it phosphorylates and inhibits retinoblastoma (RB) protein family members, playing a crucial role in regulating the cell-cycle during G1/S transition . Cyclin D3 is particularly significant in lymphocyte development, where it has specialized functions that cannot be compensated by other D-type cyclins. Research has demonstrated that cyclin D3 deficiency leads to significant developmental blocks in T and B lymphocytes, indicating its unique role in lymphopoiesis .

How does Cyclin D3 differ from other D-type cyclins in cellular function?

Cyclin D3 exhibits specialized functions in lymphocyte development that are distinct from other D-type cyclins. Studies using knockout models have demonstrated that even when cyclin D2 is expressed at high levels, it cannot rescue the developmental defects caused by cyclin D3 deficiency in early lymphocytes . Knock-in experiments where cyclin D2 was expressed from the cyclin D3 locus (Ccnd2 from the Ccnd3 locus) failed to rescue normal lymphocyte development, confirming that cyclin D3 performs unique functions . This non-redundancy extends to oncogenic transformation, where cyclin D3 plays a specific role in Notch-driven T-cell acute lymphoblastic leukemia development that cannot be replaced by cyclin D2 .

What are the typical applications for CYCD3-3 antibody in research settings?

The CYCD3-3 antibody is primarily used for detecting and quantifying cyclin D3 expression in research applications through:

• Immunofluorescent staining with flow cytometric analysis for studying expression patterns in different cell populations

• Immunohistochemistry for tissue localization studies

• Cell cycle progression analysis, particularly in G1/S transition research

• Investigation of cyclin D3 expression in malignant transformation and cancer progression

• Studying the relationship between cyclin D3 and CDK4/6 in retinoblastoma protein phosphorylation

The antibody is particularly valuable in research involving lymphocyte development, T-cell malignancies, and other cancer types where cyclin D3 dysregulation has been implicated .

What is the optimal protocol for detecting Cyclin D3 in different cellular compartments?

For comprehensive detection of cyclin D3 across cellular compartments (nucleus, cytoplasm, and cell membrane ), researchers should employ the following protocol:

• Sample preparation:

  • For adherent cells: Grow cells on coverslips, fix with 4% paraformaldehyde (10 minutes at room temperature), and permeabilize with 0.1% Triton X-100

  • For suspension cells: Fix in suspension, then prepare cytospins or adhere to poly-L-lysine coated slides

How can I validate the specificity of CYCD3-3 antibody in my experimental system?

Validation of CYCD3-3 antibody specificity should include multiple complementary approaches:

• Positive and negative controls:

  • Positive control: Cells known to express high levels of cyclin D3 (e.g., proliferating lymphocytes)

  • Negative control: Cells with confirmed absence of cyclin D3 (e.g., Ccnd3 knockout models)

  • Isotype control: Use mouse IgG1, κ (matching the antibody isotype) to assess non-specific binding

• Molecular validation:

  • Western blot analysis to confirm detection of a single band at the expected molecular weight (33 kDa)

  • RNA interference: siRNA knockdown of cyclin D3 should reduce antibody signal

  • Competitive inhibition: Pre-incubation with purified cyclin D3 protein should block antibody binding

• Cross-reactivity assessment:

  • Test antibody reactivity in cells overexpressing related cyclins (D1, D2)

  • Verify species cross-reactivity (confirmed for human, mouse, and rat)

• Functional correlation:

  • Correlate cyclin D3 detection with cell cycle phase (highest in G1/S transition)

  • Compare with alternative anti-cyclin D3 antibody clones

Combining these validation steps ensures reliable and specific detection of cyclin D3 in your experimental system.
