What is the function of this protein?
Myosins are actin-based motor molecules with ATPase activity.  Unconventional myosins serve in intracellular movements.  Binds actin with high affinity both in the absence and presence of ATP and its mechanochemical activity is inhibited by calcium ions.  Also acts as a GTPase activator for RHOA.  Plays a role in the regulation of cell migration via its role as RHOA GTPase activator.  This is regulated by its interaction with the SLIT2 receptor ROBO1; interaction with ROBO1 impairs interaction with RHOA and subsequent activation of RHOA GTPase activity, and thereby leads to increased levels of active, GTP-bound RHOA.
What are the official names of this protein?
Unconventional myosin-IXb, Unconventional myosin-9b.
What is the protein family that this protein belongs to?
Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Myosin family.
What are the subcellular locations of this protein?
Cytoplasm, cell cortex. Cytoplasm, perinuclear region. Cytoplasm, cytoskeleton. Note=In undifferentiated cells colocalizes with F-actin in the cell periphery while in differentiated cells its localization is cytoplasmic with the highest levels in the perinuclear region.
