ZKSCAN5 Antibody
Description
Definition and Purpose
ZKSCAN5 antibodies are specialized reagents designed to detect and study the zinc finger protein with KRAB and SCAN domains 5 (ZKSCAN5), a transcription factor implicated in cancer progression and lymphangiogenesis . These antibodies are critical tools for research in oncology, immunology, and molecular biology, enabling the visualization and quantification of ZKSCAN5 in tissues and cells.
Structure and Function of ZKSCAN5
ZKSCAN5 is a nuclear protein containing 13 C2H2-type zinc fingers, a KRAB A domain, and a SCAN box domain . It regulates gene expression by recruiting histone-modifying enzymes like SETD7 to DNA, as demonstrated in breast cancer models . Overexpression of ZKSCAN5 correlates with poor prognosis in breast cancer patients, making it a key biomarker for aggressive disease states .
Applications of ZKSCAN5 Antibodies
ZKSCAN5 antibodies are used in:
Research Insights
-
ZKSCAN5-SETD7 Interaction: ZKSCAN5 recruits SETD7 to the VEGFC promoter, enhancing transcription and lymphangiogenesis .
-
Tumor Growth: Knockdown of ZKSCAN5 in breast cancer models reduces tumor size and lung metastasis .
-
Alternative Splicing: Three splice variants exist, with one specific to testis .
Challenges and Considerations
-
Cross-Reactivity: Recombinant proteins may not be detected due to tertiary structure differences .
-
Storage: Antibodies require −20°C storage and controlled handling .
Future Directions
-
Diagnostic Assays: Development of ZKSCAN5-based biomarkers for breast cancer screening.
-
Therapeutic Antibodies: Targeting ZKSCAN5 to inhibit tumor growth and metastasis.
This antibody remains a cornerstone for advancing our understanding of ZKSCAN5’s role in oncology, offering insights into personalized medicine and cancer biology.
