EOG89PDCD GO:0016021 3/105 integral component of membrane cellular_component "The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane." [GOC:dos, GOC:go_curators] EOG89PDCD GO:0004721 2/105 phosphoprotein phosphatase activity molecular_function "Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. Together with protein kinases, these enzymes control the state of phosphorylation of cell proteins and thereby provide an important mechanism for regulating cellular activity."

[GOC:bf, GOC:mtg_sensu] EOG89PDCD GO:0007424 1/105 open tracheal system development biological_process "The process whose specific outcome is the progression of an open tracheal system over time, from its formation to the mature structure. An open tracheal system is a respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues via spiracles. An example of this is found in Drosophila melanogaster." [GOC:mtg_sensu, PMID:8625828] EOG89PDCD GO:0035151 1/105 regulation of tube size, open tracheal system biological_process "Ensuring that an epithelial tube in an open tracheal system is of the correct length and diameter. Tracheal tubes undergo highly regulated tube-size increases during development, expanding up to 40 times their initial size by the end of larval life. Tube size appears to be controlled by regulation of apical membrane expansion and secretion, rather than by changes in cell number, size or shape."
