MYBL Antibodies

MYBL antibodies are specific reagents used to detect and study the expression, localization, and activity of MYBL proteins in cells and tissues. These antibodies are used in research focusing on transcriptional regulation, cell cycle control, and cancer biology, especially in cases where MYBL dysregulation contributes to uncontrolled cell growth and tumorigenesis.

Applications of MYBL Antibodies

• Western Blotting (WB): MYBL antibodies are frequently used in Western blot assays to detect the expression levels of MYBL proteins in cell and tissue lysates. Researchers often use MYBL antibodies to examine changes in expression during cell cycle progression or under conditions of cellular stress or tumorigenesis.
• Immunohistochemistry (IHC): In IHC, MYBL antibodies enable the localization of MYBL proteins in tissue sections. This application is valuable for studying the role of MYBL proteins in the differentiation and proliferation of specific cell types, especially in cancerous tissues where MYBL overexpression may be observed.
• Immunoprecipitation (IP): MYBL antibodies are employed in immunoprecipitation experiments to isolate MYBL proteins from cellular extracts. This approach helps researchers investigate protein-DNA interactions or protein-protein interactions involving MYBL, allowing for the study of its regulatory role in gene expression and transcriptional complexes.

Key MYBL Proteins Targeted by Antibodies

• MYBL1 (A-Myb): MYBL1 is involved in regulating transcription in tissues with high proliferative activity, such as reproductive tissues, and plays roles in spermatogenesis and mammary gland development. Dysregulation of MYBL1 has been linked to certain cancers, including lymphomas and breast cancer.
• MYBL2 (B-Myb): MYBL2 is expressed in proliferating cells and is essential for cell cycle progression, particularly in regulating the G2/M transition. MYBL2 overexpression is frequently observed in various cancers, including breast, colorectal, and hematological cancers. Due to its role in cell cycle regulation, MYBL2 is considered a potential therapeutic target in cancer treatment.
• MYBL3 (C-Myb-like protein): Though less well characterized than MYBL1 and MYBL2, MYBL3 is thought to share functional similarities with other MYBL proteins, contributing to the regulation of proliferation and differentiation in certain cell types.

MYBL antibodies are essential tools in studying the roles of MYBL proteins in transcriptional regulation, cell cycle control, and cancer biology. These antibodies enable researchers to detect, quantify, and localize MYBL proteins, providing insights into how these transcription factors contribute to normal cellular processes and disease progression, particularly in cancer.
