Facts about Unconventional myosin-Ig.
Acts as a regulator of T-cell migration by generating membrane tension, enforcing cell-intrinsic meandering search, thereby enhancing detection of rare antigens through lymph-node surveillance, enabling pathogen eradication. Also required in B- cells, where it regulates different membrane/cytoskeleton- dependent procedures.

Specifically expressed in hematopoietic cells.
Cell membrane; Peripheral membrane protein. Cell projection, phagocytic cup. Recruited to Fc-gamma receptor (Fc-gamma-R) phagocytic cup. In T-cells, transiently accumulates in discrete areas at the plasma membrane of migrating cells or when membranes are deformed (By similarity). Localization at the membrane is not highly dependent on phosphatidylinositol 4,5-bisphosphate levels. Released from the membrane in the presence of ATP. May be enriched in peripheral processes, such as microvilli or ruffles.
