Human Gene MOB1B (uc003hfw.3) Description and Page Index
  Description: Homo sapiens MOB kinase activator 1B (MOB1B), transcript variant 2, mRNA.
RefSeq Summary (NM_173468): The protein encoded by this gene is similar to the yeast Mob1 protein. Yeast Mob1 binds Mps1p, a protein kinase essential for spindle pole body duplication and mitotic checkpoint regulation. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011].

DESCRIPTION: RecName: Full=MOB kinase activator 1B; AltName: Full=Mob1 homolog 1A; Short=Mob1A; AltName: Full=Mob1B; AltName: Full=Mps one binder kinase activator-like 1A;
FUNCTION: Activator of LATS1/2 in the Hippo signaling pathway which plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein STK3/MST2 and STK4/MST1, in complex with its regulatory protein SAV1, phosphorylates and activates LATS1/2 in complex with its regulatory protein MOB1, which in turn phosphorylates and inactivates YAP1 oncoprotein and WWTR1/TAZ. Phosphorylation of YAP1 by LATS1/2 inhibits its translocation into the nucleus to regulate cellular genes important for cell proliferation, cell death, and cell migration. Stimulates the kinase activity of STK38L.
SUBUNIT: Binds STK38L. Interacts with LATS1 and LATS2.
INTERACTION: O95835:LATS1; NbExp=2; IntAct=EBI-2558745, EBI-444209; Q9NRM7:LATS2; NbExp=2; IntAct=EBI-2558745, EBI-3506895;
TISSUE SPECIFICITY: Adrenal gland, bone marrow, brain, lung, placenta, prostate, salivary gland, skeletal muscle, testis, thymus, thyroid gland, uterus, colon with mucosa, fetal brain and fetal liver.
PTM: Phosphorylated by STK3/MST2 and STK4/MST1 and this phosphorylation enhances its binding to LATS1.
SIMILARITY: Belongs to the MOB1/phocein 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.

ModBase Predicted Comparative 3D Structure on Q7L9L4
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.
