ID:ODF3A_HUMAN DESCRIPTION: RecName: Full=Outer dense fiber protein 3; AltName: Full=Outer dense fiber of sperm tails protein 3; AltName: Full=Sperm tail protein SHIPPO 1; AltName: Full=Transcript induced in spermiogenesis protein 50; FUNCTION: Outer dense fibers are filamentous structures located on the outside of the axoneme in the midpiece and principal piece of the mammalian sperm tail. May help to maintain the passive elastic structures and elastic recoil of the sperm tail. SUBCELLULAR LOCATION: Cytoplasm (By similarity). Note=Expressed in the cytoplasmic lobe of spermatids (By similarity). TISSUE SPECIFICITY: Testis-specific. MISCELLANEOUS: 'Shippo' is a Japanese word for tail. SIMILARITY: Belongs to the ODF3 family. SIMILARITY: Contains 2 STPGR (Sperm-tail PG-rich) 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.
ModBase Predicted Comparative 3D Structure on Q96PU9
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.
