CARMIL1 (Capping Protein Regulator and Myosin 1 Linker 1): CARMIL1 is a gene that encodes a protein involved in regulating actin dynamics, a crucial component of the cellular cytoskeleton. It plays a significant role in cell movement, structure, and signaling. Alterations or disruptions in CARMIL1 can affect cell motility and have been linked to immune system dysfunction and certain types of cancer.
