ID:SIAL_HUMAN DESCRIPTION: RecName: Full=Bone sialoprotein 2; AltName: Full=Bone sialoprotein II; Short=BSP II; AltName: Full=Cell-binding sialoprotein; AltName: Full=Integrin-binding sialoprotein; Flags: Precursor; FUNCTION: Binds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction. Promotes Arg-Gly-Asp-dependent cell attachment. SUBCELLULAR LOCATION: Secreted. PTM: N-glycosylated; glycans consist of sialylated and core- fucosylated bi-, tri- and tetraantennary chains. PTM: O-glycosylated at eight sites; mucin-type glycans contain Gal, GlcNAc, GalNAc and terminal NeuAc. PTM: Sulfated on either Tyr-313 or Tyr-314. MISCELLANEOUS: It is possible that the segments of clustered carboxyl groups mediate the strong binding to hydroxyapatite.
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.
