BMX kinase belongs to the Tec family of tyrosine kinases, characterized by SH3, SH2 domains, and a tyrosine kinase catalytic domain. It is primarily expressed in the cardiovascular system, immune cells, and certain cancer cells. BMX plays a crucial role in regulating cell signal transduction by participating in receptor kinase signaling pathways such as EGFR, VEGFR, affecting cell migration, proliferation, and survival. The activity and expression of BMX are regulated during inflammation, angiogenesis, and tumor development. The specific expression pattern of BMX and potential gene mutations are associated with the occurrence and progression of various diseases, including cancer and cardiovascular diseases, making it a potential therapeutic target.
