Bruton’s tyrosine kinase (BTK) is a member of the Tec tyrosine kinase family, which is expressed in most hematopoietic cells such as B cells, myeloid cell, mast cells, and macrophage. BTK is a kinase that plays a crucial role in B-cell signaling pathway, which is an important downstream mediator of NF-κB and MAPK signaling pathways, which are strongly associated with cancer. Therefore, BTK is a promising biological target for therapeutic intervention of autoimmune diseases and cancer/B cell malignancies.
