Descriptions

MOB1A is a multifunctional protein involved in key signaling pathways like Hippo and NDR pathway signaling in metazoans and the Mitotic Exit Network in yeast. It regulates protein interactions by binding to upstream kinases MST1 and MST2 and downstream AGC group kinases LATS1, LATS2, NDR1, and NDR2. The autoinhibition of MOB1A occurs when its nonphosphorylated N-terminal extension binds to the core domain, blocking the kinase-binding site. This inhibitory interaction is relieved upon phosphorylation at specific sites (T12 and T35), which induces a conformational change that exposes the kinase-binding surface. Phosphorylation of MOB1A at T12 and T35 is crucial for regulating its interactions with both upstream and downstream kinases. The phosphorylation status dictates the binding affinity of MOB1A, enabling or inhibiting interactions with other proteins. The phosphorylation-dependent conformational changes in MOB1A are essential for the proper functioning of the Hippo signaling pathway, which is critical for cell proliferation and tissue growth regulation.

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.
