MYPOP (Myb-related transcription factor partner): MYPOP is a key regulator that interacts with Myb-related transcription factors to modulate gene expression. Similar to MMP15’s role in the extracellular matrix, MYPOP plays a vital part in controlling cellular processes such as proliferation, differentiation, and cell cycle progression. Through its influence on transcriptional regulation, MYPOP impacts important physiological functions including tissue development, immune response, and maintenance of homeostasis. Dysregulation of MYPOP has been linked to various pathological conditions, including cancer, developmental disorders, and immune diseases.
