-  Comments and Description Text from UniProtKB
  ID: KLHL9_HUMAN
DESCRIPTION: RecName: Full=Kelch-like protein 9;
FUNCTION: Substrate-specific adapter of a BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complex required for mitotic progression and cytokinesis. The BCR(KLHL9-KLHL13) E3 ubiquitin ligase complex mediates the ubiquitination of AURKB and controls the dynamic behavior of AURKB on mitotic chromosomes and thereby coordinates faithful mitotic progression and completion of cytokinesis.
PATHWAY: Protein modification; protein ubiquitination.
SUBUNIT: Component of the BCR(KLHL9-KLHL13) E3 ubiquitin ligase complex, at least composed of CUL3, KLHL9, KLHL13 and RBX1. Interacts with AURKB.
SIMILARITY: Contains 1 BACK (BTB/Kelch associated) domain.
SIMILARITY: Contains 1 BTB (POZ) domain.
SIMILARITY: Contains 6 Kelch repeats.
SEQUENCE CAUTION: Sequence=BAA92592.1; Type=Erroneous initiation;

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.
