ID:UN45A_HUMAN DESCRIPTION: RecName: Full=Protein unc-45 homolog A; Short=Unc-45A; AltName: Full=GCUNC-45; AltName: Full=Smooth muscle cell-associated protein 1; Short=SMAP-1; FUNCTION: Acts as co-chaperone for HSP90. Prevents the stimulation of HSP90AB1 ATPase activity by AHSA1. Positive factor in promoting PGR function in the cell. May be necessary for proper folding of myosin (Potential). Necessary for normal cell proliferation. Necessary for normal myotube formation and myosin accumulation during muscle cell development. May play a role in erythropoiesis in stroma cells in the spleen (By similarity). SUBUNIT: Interacts with PGR isoforms A and B as well as with NR3C1 in the absence of ligand, and with HSP90AB1. Binding to HSP90AB1 involves 2 UNC45A monomers per HSP90AB1 dimer. SUBCELLULAR LOCATION: Cytoplasm. Cytoplasm, perinuclear region. Nucleus. Note=Predominant in the perinuclear region. Little protein in the nucleus. TISSUE SPECIFICITY: Detected in peripheral blood leukocytes, bone marrow, adrenal gland, trachea, spinal cord, thyroid, lymph node and stomach. SIMILARITY: Contains 3 TPR repeats.
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.
