BANK1, also known as B-cell scaffold protein with ankyrin repeats 1, is a protein predominantly expressed in B lymphocytes, a type of white blood cell crucial for adaptive immunity. BANK1 plays a significant role in modulating B-cell receptor (BCR) signaling, a pivotal process in the activation and differentiation of B cells. One of the primary functions of BANK1 is its involvement in BCR signaling pathway regulation. BANK1 acts as a scaffold protein, facilitating the assembly of signaling complexes upon BCR engagement. It interacts with various signaling molecules, including kinases, phosphatases, and adapter proteins, thereby modulating downstream signaling cascades. Through its scaffolding...
