ID:PHB_HUMAN DESCRIPTION: RecName: Full=Prohibitin; FUNCTION: Prohibitin inhibits DNA synthesis. It has a role in regulating proliferation. As yet it is unclear if the protein or the mRNA exhibits this effect. May play a role in regulating mitochondrial respiration activity and in aging. SUBUNIT: Interacts with PHB2. INTERACTION: Q496Y0:LONRF3; NbExp=2; IntAct=EBI-354213, EBI-2690768; O14980:XPO1; NbExp=2; IntAct=EBI-354213, EBI-355867; SUBCELLULAR LOCATION: Mitochondrion inner membrane (By similarity). TISSUE SPECIFICITY: Widely expressed in different tissues. DEVELOPMENTAL STAGE: Levels of expression in fibroblasts decrease heterogeneously during cellular aging. INDUCTION: Expression increases approximately 3-fold upon entry into G1 phase compared with other phases of the cell cycle. Also induced following inhibition of mitochondrial protein synthesis by thiamphenicol. SIMILARITY: Belongs to the prohibitin family.
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.
