ID:FBX43_HUMAN DESCRIPTION: RecName: Full=F-box only protein 43; AltName: Full=Endogenous meiotic inhibitor 2; FUNCTION: Required to establish and maintain the arrest of oocytes at the second meiotic metaphase until fertilization. Probably acts by inhibiting the anaphase-promoting complex/cyclosome (APC/C) ubiquitin ligase. Probably recognizes and binds to some phosphorylated proteins and promotes their ubiquitination and degradation (Probable). PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: Part of a SCF (SKP1-cullin-F-box) protein ligase complex. May interact with CDC20 (By similarity). PTM: Phosphorylated on Ser-76, Thr-234 and Ser-334 in response to calcium, which is a prerequisite for ubiquitination and proteasomal degradation (Probable). PTM: Ubiquitinated in response to calcium, which promotes proteasomal degradation. SIMILARITY: Contains 1 F-box domain. SIMILARITY: Contains 1 IBR-type zinc finger.
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.
