ID:FBX2_HUMAN DESCRIPTION: RecName: Full=F-box only protein 2; FUNCTION: Substrate recognition component of a SCF (SKP1-CUL1-F- box protein) E3 ubiquitin-protein ligase complex that mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Involved in the endoplasmic reticulum-associated degradation pathway (ERAD) for misfolded lumenal proteins by recognizing and binding sugar chains on unfolded glycoproteins that are retrotranslocated into the cytosol and promoting their ubiquitination and subsequent degradation. Prevents formation of cytosolic aggregates of unfolded glycoproteins that have been retrotranslocated into the cytosol. Able to recognize and bind denatured glycoproteins, preferentially those of the high-mannose type (By similarity). PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: Component of the SCF(FBXO2) complex consisting of CUL1, RBX1, SKP1 and FBXO2. Predominantly detected as heterodimer with SKP1; the heterodimer with SKP1 is not part of the SCF(FBXO2) complex (By similarity). SUBCELLULAR LOCATION: Cytoplasm (By similarity). Microsome membrane; Peripheral membrane protein; Cytoplasmic side (By similarity). SIMILARITY: Contains 1 F-box domain. SIMILARITY: Contains 1 FBA (F-box associated) 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.
