Descriptions

MOB1 protein is a key regulator of large tumor suppressor 1/2 (LATS1/2) kinases in the Hippo pathway. Full-length MOB1B is in the autoinhibited form, showing that the N-terminal extension blocks the LATS1 binding surface of MOB2B. Phosphorylation of Thr12 and Thr35 residues accelerates dissociation of the Switch helix from the LATS1-binding surface by the pull-the-string mechanism, thereby enabling LATS1 binding.

2 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
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
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.
signal transduction The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
