Activity summary

The c-Myb protein also known as Myb MYB or c-myb acts mechanically as a transcription factor that regulates the expression of target genes. It plays a role in cellular processes like proliferation differentiation and apoptosis by binding to specific DNA sequences. c-Myb has a molecular mass of roughly 75 kDa. It predominantly expresses in hematopoietic cells where it significantly influences gene transcription activity. Also it appears in some epithelial tissues indicating its versatile role in different cell types.

Biological function summary

The protein serves as a master regulator in the development of various cell types. It is not part of a traditional complex but interacts with other proteins to exert its function such as binding with co-activators or repressors to modulate gene expression. c-Myb controls the transcription of genes that are critical for cell cycle regulation and differentiation especially in the context of blood cell lineages. The protein is particularly influential in the production of red blood cells and white blood cells.

Pathways

C-Myb fits integrally into known hematopoietic signaling cascades and the Wnt signaling pathway. It works alongside other proteins like cyclin-dependent kinase (CDK) family members and transcription factor GATA-1 to modulate lineage-specific gene expression. Through its regulatory actions c-Myb influences the activation of downstream effectors that propagate signals essential for maintaining cellular functions within these pathways. The modulation of these pathways underlines its role in cell fate decisions.

Associated diseases and disorders

Studies link c-Myb to several forms of leukemia and colon cancer. In leukemia aberrant expression of c-Myb disrupts normal hematopoiesis contributing to the uncontrolled proliferation of immature blood cells. The abnormal interactions between c-Myb and proteins like Bcl-2 can lead to enhanced cellular survival further promoting malignant conditions. In colon cancer c-Myb overexpression influences tumor growth and progression often acting alongside other oncogenic factors to enhance disease severity.
