  ID: C1QBP_HUMAN
DESCRIPTION: RecName: Full=Complement component 1 Q subcomponent-binding protein, mitochondrial; AltName: Full=GC1q-R protein; AltName: Full=Glycoprotein gC1qBP; Short=C1qBP; AltName: Full=Hyaluronan-binding protein 1; AltName: Full=Mitochondrial matrix protein p32; AltName: Full=p33; Flags: Precursor;
FUNCTION: Binds to the globular "heads" of C1Q thus inhibiting C1 activation.
SUBUNIT: Interacts with Rubella virus capsid protein. Interacts with HIV-1 Tat. Interacts with CDK13. Interacts with HRK.
SUBCELLULAR LOCATION: Mitochondrion matrix. Nucleus. Note=Might also be nuclear in some cell types.
SIMILARITY: Belongs to the MAM33 family.
CAUTION: Was originally (PubMed:1830244 and PubMed:8262387) thought to be a pre-mRNA splicing factor SF2 p32 subunit and to play a role in preventing exon skipping, ensuring the accuracy of splicing and regulating alternative splicing.

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.
