ID:MY18B_HUMAN DESCRIPTION: RecName: Full=Unconventional myosin-XVIIIb; 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. SUBUNIT: Homodimer. May interact with F actin through the GPA motif (Gly/Pro/Ala-rich). 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. TISSUE SPECIFICITY: Selectively expressed in cardiac and skeletal muscles. Weakly expressed in testis, pancreas, placenta, prostate, lung and thymus. DEVELOPMENTAL STAGE: Reaches an expression peak in the third day after induction and remains at similar level during successive myotubule maturation. MISCELLANEOUS: Frequently deleted, mutated, and hypermethylated in lung cancers. SIMILARITY: Contains 1 IQ domain. SIMILARITY: Contains 1 myosin head-like domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
