  • GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
  • GO:0008934 Catalysis of the reaction: 1D-myo-inositol 1-phosphate + H2O = myo-inositol + phosphate.
  • GO:0046872 Binding to a metal ion.
  • GO:0003723 Binding to an RNA molecule or a portion thereof.
  • GO:0006020 The chemical reactions and pathways involving inositol, 1,2,3,4,5,6-cyclohexanehexol, a growth factor for animals and microorganisms.
  • GO:0046854 The chemical reactions and pathways resulting in the formation of phosphatidylinositol phosphate.
  • GO:0042254 A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of ribosome subunits; includes transport to the sites of protein synthesis.
  • GO:0007165 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.
  • GO:0031564 A positive regulation of gene expression mechanism that allows RNA polymerase to continue transcription beyond a termination site, thus allowing expression of downstream genes under specific conditions.
