The MYB protein family, named after the myeloblastosis viral oncogene homolog, comprises a group of evolutionarily conserved transcription factors critical for regulating cellular processes in eukaryotes. Human MYB proteins, including c-MYB, A-MYB, and B-MYB, are characterized by a highly conserved N-terminal R2R3-type DNA-binding domain that recognizes specific promoter sequences to modulate gene expression. These proteins play pivotal roles in cell cycle progression, differentiation, apoptosis, and stem cell maintenance. c-MYB is prominently expressed in hematopoietic tissues and is essential for T-cell development and erythropoiesis, while A-MYB and B-MYB exhibit tissue-specific roles in mammary gland development and spermatogenesis, respectively. Dysregulation of MYB proteins is implicated in various cancers, acting as oncogenes (e.g., c-MYB in leukemia) or tumor suppressors depending on context. For instance, MYB overexpression drives proliferation in colorectal and breast cancers, whereas its loss promotes genomic instability. Recombinant human MYB proteins, typically produced via bacterial or mammalian expression systems, enable mechanistic studies of MYB-DNA/cofactor interactions and pathway modulation. They are vital tools for screening MYB-targeted therapies, particularly for cancers resistant to conventional treatments. Current research focuses on elucidating post-translational modifications, isoform-specific functions, and therapeutic strategies to modulate MYB activity in disease.
