| GO:0035091 | phosphatidylinositol binding | molecular_function | Binding to an inositol-containing glycerophospholipid, i.e. phosphatidylinositol (PtdIns) and its phosphorylated derivatives. [GOC:bf, ISBN:0198506732, PMID:11395417] |
| GO:0005524 | ATP binding | molecular_function | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. [ISBN:0198506732] |
| GO:0007165 | signal transduction | biological_process | 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. [GOC:go_curators, GOC:mtg_signaling_feb11] |

| GO:0016772 | transferase activity, transferring phosphorus-containing groups | molecular_function | Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to another (acceptor). [GOC:jl, ISBN:0198506732] |
| GO:0140096 | catalytic activity, acting on a protein | molecular_function | Catalytic activity that acts to modify a protein. [GOC:molecular_function_refactoring, GOC:pdt] |
| GO:0006468 | protein phosphorylation | biological_process | The process of introducing a phosphate group on to a protein. [GOC:hb] |
| GO:0004712 | protein serine/threonine/tyrosine kinase activity | molecular_function | Catalysis of the reactions |
| GO:0016020 | membrane | cellular_component | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. [GOC:dos, GOC:mah, ISBN:0815316194] |
| GO:0005764 | lysosome | cellular_component | A small lytic vacuole that has cell cycle-independent morphology found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions. [GOC:mah, ISBN:0198506732] |
| GO:0005769 | early endosome | cellular_component | A membrane-bounded organelle that receives incoming material from primary endocytic vesicles that have been generated by clathrin-dependent and clathrin-independent endocytosis; vesicles fuse with the early endosome to deliver cargo for sorting into recycling or degradation pathways. [GOC:mah, NIF_Subcellular:nlx_subcell_20090701, PMID:19696797] |
| GO:0016301 | kinase activity | molecular_function | Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule. [ISBN:0198506732] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0016773 | phosphotransferase activity, alcohol group as acceptor | molecular_function | Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to an alcohol group (acceptor). [GOC:jl] |
| GO:0016740 | transferase activity | molecular_function | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. [ISBN:0198506732] |
| GO:0003824 | catalytic activity | molecular_function | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.

| GO:0004672 | protein kinase activity | molecular_function | Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction |
| GO:0005768 | endosome | cellular_component | A vacuole to which materials ingested by endocytosis are delivered. [ISBN:0198506732, PMID:19696797] |
