ID:SRP54_HUMAN DESCRIPTION: RecName: Full=Signal recognition particle 54 kDa protein; Short=SRP54; FUNCTION: Binds to the signal sequence of presecretory protein when they emerge from the ribosomes and transfers them to TRAM (translocating chain-associating membrane protein). SUBUNIT: Signal recognition particle consists of a 7S RNA molecule of 300 nucleotides and six protein subunits: SRP72, SRP68, SRP54, SRP19, SRP14 and SRP9. Interacts with RNPS1. SUBCELLULAR LOCATION: Nucleus speckle. Cytoplasm. DOMAIN: Has a two domain structure: the G-domain binds GTP; the M- domain binds the 7S RNA in presence of SRP19 and also binds the signal sequence. SIMILARITY: Belongs to the GTP-binding SRP family. SRP54 subfamily.

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.
