Protein: Unconventional myosin-XVIIIb (Q8IUG5)
Organism: Homo sapiens (Human)
Function: May be involved in intracellular trafficking of the muscle cell when in the cytoplasm, whereas entering the nucleus, may be involved in the regulation of muscle specific genes. May play a role in the control of tumor development and progression; restored MYO18B expression in lung cancer cells suppresses anchorage-independent growth.
Subcellular location: Cytoplasm. Nucleus. Cytoplasm, myofibril, sarcomere. Note=Punctate pattern in undifferentiated myoblasts. Nuclear, on primary cardiomyocytes and adult muscle. A partial sarcomeric location was found in some cardiomyocytes.
