Descriptions

Mob1 is an 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. Mob1 adopts an autoinhibited, closed conformation, with its N-terminal FXFx5KxF motif. Phosphorylation of Mob1 at T35 relieves this autoinhibition and stimulates Lats1 binding in part.

4 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
extracellular exosome A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

2 GO annotations of molecular function

Name Definition
metal ion binding Binding to a metal ion.
protein kinase activator activity Binds to and increases the activity of a protein kinase, an enzyme which phosphorylates a protein.

2 GO annotations of biological process

Name Definition
hippo signaling The series of molecular signals mediated by the serine/threonine kinase Hippo or one of its orthologs. In Drosophila, Hippo in complex with the scaffold protein Salvador (Sav), phosphorylates and activates Warts (Wts), which in turn phosphorylates and inactivates the Yorkie (Yki) transcriptional activator. The core fly components hippo, sav, wts and mats are conserved in mammals as STK4/3 (MST1/2), SAV1/WW45, LATS1/2 and MOB1.
positive regulation of protein phosphorylation Any process that activates or increases the frequency, rate or extent of addition of phosphate groups to amino acids within a protein.
