Description

WASF3 Function

WASF3 (Wiskott-Aldrich syndrome protein family member 3) is a cytoskeletal regulator critical for actin polymerization, cell migration, and cancer invasion. It interacts with the WASF regulatory complex (WRC), including CYFIP1, to modulate membrane protrusions and metastasis . Overexpression of WASF3 correlates with aggressive cancer phenotypes, including prostate, breast, and lung cancers .

Role of the FITC-Conjugated Antibody

This antibody enables precise detection of WASF3 in:

  • Immunofluorescence (IF): Tracking WASF3 localization in subcellular compartments (e.g., membrane protrusions, cytoplasm).

  • Western Blotting (WB): Quantifying WASF3 expression levels in lysates.

  • ELISA: Validating WASF3 protein presence in complex biological matrices .

Cancer Progression and Metastasis

  • Prostate Cancer: WASF3 knockdown reduces cell motility, invasion, and metastasis, with downregulated MMP-9 expression .

  • Breast Cancer: WASF3 depletion suppresses anchorage-independent growth and tumor formation in xenograft models .

  • Lung Cancer: Higher WASF3 expression in adenocarcinoma correlates with poor prognosis and advanced stages .

Mechanistic Insights

  • WASF3-CYFIP1 Interaction: Stapled peptides targeting this interface disrupt WASF3 activation, reducing Rac signaling and metastatic potential .

  • Small-Molecule Inhibitors: Compounds like N20 inhibit WASF3-mediated invasion without affecting viability, highlighting therapeutic potential .

Target Background

Function
WASF3 (Wiskott-Aldrich syndrome protein family member 3) is a downstream effector molecule involved in signal transduction from tyrosine kinase receptors and small GTPases to the actin cytoskeleton. It plays a crucial role in regulating cell morphology and cytoskeletal organization, ultimately contributing to the control of cell shape.
Gene References Into Functions
  1. A study revealed significantly elevated levels of WAVE3 expression in pancreatic cancer tissues compared to non-cancerous tissues. This upregulation appears to be associated with lymphatic metastasis and poorly differentiated tumors. Moreover, the findings suggest that WAVE3 influences cell proliferation, migration, and invasion through the AKT pathway. PMID: 29845225
  2. Research indicates that Wiskott-Aldrich syndrome verprolin-homologous protein 3 (WAVE3) might play a pivotal role in ovarian cancer cell motility, invasion, and oncogenesis. PMID: 28476025
  3. p63alpha protein upregulates heat shock protein 70 expression via E2F1 transcription factor 1, promoting Wasf3/Wave3/MMP9 signaling and bladder cancer invasion. PMID: 28794159
  4. Research demonstrates that WASF3 is present in the HER2 immunocomplex, and suppressing WASF3 function leads to suppression of invasion even in the presence of HER2 expression. The engagement of WASF3 with the HER2/HER3 complex facilitates its phospho-activation and transcriptional upregulation, which is facilitated by HER2/HER3 activation of JAK/STAT signaling. PMID: 26804171
  5. It was concluded that WAVE3 may represent a new adverse prognostic factor for patients with intrahepatic cholangiocarcinoma (ICC). PMID: 26971088
  6. Studies provide a deeper understanding of the crucial role of WASF3 in facilitating increased invasion potential in cancer cells expressing mutant RAS, supporting the idea that targeting WASF3 in metastatic cells overexpressing RAS may be used to suppress invasion and metastasis. PMID: 28233357
  7. Results implicate a contributory role of WAVE1 and -3 to the metastatic phenotype of PC-3 cells through their interaction with the ARP2/3 complex. PMID: 26977009
  8. Stabilization of WASF3 function occurs through its interaction with ATAD3A and GRP78, which may provide a bridge between the endoplasmic reticulum (ER) and mitochondria, allowing communication between the two organelles. PMID: 25823022
  9. Research demonstrates that WAVE3-mediated modulation of NFkappaB is required for invadopodia formation, as well as MMP9 expression and activity, which are necessary for cancer cells to degrade the extracellular matrix (ECM). PMID: 25329315

  15. These results define a novel signaling network whereby JAK2/STAT3 signaling creates a feed-forward loop to raise activated WASF3 levels that promote cancer cell motility. PMID: 23677069
  16. MMP-9 and WAVE3 were overexpressed in colorectal cancer tissues compared to normal mucosa. PMID: 22806308

  19. WAVE3-depleted breast cancer cells move more slowly but more persistently on a 2-dimensional matrix. They typically only show one lamellipod. WAVE3 appears to have no role in driving invasiveness. Lamellipodial persistence is not crucial in 3-dimensions. PMID: 22909346
  20. HSP90 and HSP70 proteins are essential for stabilization and activation of WASF3, a metastasis-promoting protein. PMID: 22315230
  21. Coordinated expression patterns of the WASF3 metastasis promoter gene and the KISS1 metastasis suppressor gene appear to exert their influence through inhibition of NF-kappaB signaling, which in turn regulates MMP-9 production facilitating invasion. PMID: 21544801
  22. The study also identifies a critical role for WAVE3, downstream of miR-31, in the invasion-metastasis cascade. PMID: 21105030
