Supplementary information

Non-muscle Myosin IIA also known as Myosin Heavy Chain 9 or Myosin-9 is a motor protein that enables cellular mechanical tasks such as actin filament cross-linking and contraction. It has a molecular mass of approximately 226 kDa. Myosin IIA is expressed in a variety of cell types including epithelial cells fibroblasts and leukocytes where it contributes to various cellular activities. Myosin staining often reveals its localization at the leading edge of migrating cells revealing its involvement in cell movement.
Biological function summary

Non-muscle Myosin IIA plays an essential role in maintaining cell shape and promoting cell division. It combines with other myosin proteins into a complex often in conjunction with actin filaments. This myosin protein group further facilitates processes like cytokinesis and cellular migration. Myosin IIA's complex interactions allow cells to adapt to different mechanical stresses ensuring that cells can move and divide properly within the tissue architecture.

Pathways

Non-muscle Myosin IIA participates in both the RhoA/ROCK pathway and the actin cytoskeleton regulation pathway. Through these pathways Myosin IIA interacts with other key proteins such as Rho-associated protein kinase to mediate several cellular functions like cell shape changes and motility. These interactions allow Myosin IIA to efficiently transmit mechanical signals and respond to extracellular stimuli.

Research links non-muscle Myosin IIA with specific conditions like cancer invasion and cardiovascular disorders. Abnormal function or expression of Myosin IIA can contribute to altered cell motility resulting in cancer metastasis. Additionally mutations or disruptions in Myosin IIA can associate with conditions such as thrombocytopenia. Proteins like integrins interact with Myosin IIA in these disease states highlighting their critical roles in pathological settings.

Target data

Cellular myosin that appears to play a role in cytokinesis, cell shape, and specialized functions such as secretion and capping. Required for cortical actin clearance prior to oocyte exocytosis (By similarity). Promotes cell motility in conjunction with S100A4 (PubMed : 16707441). During cell spreading, plays an important role in cytoskeleton reorganization, focal contact formation (in the margins but not the central part of spreading cells), and lamellipodial retraction; this function is mechanically antagonized by MYH10 (PubMed : 20052411).. (Microbial infection) Acts as a receptor for herpes simplex virus 1/HHV-1 envelope glycoprotein B.
