| GO:0005886 | plasma membrane | cellular_component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
| GO:0050919 | negative chemotaxis | biological_process | The directed movement of a motile cell or organism towards a lower concentration of a chemical. [GOC:ai, GOC:bf, GOC:isa_complete] |
| GO:0030335 | positive regulation of cell migration | biological_process | Any process that activates or increases the frequency, rate or extent of cell migration. [GOC:go_curators] |
| GO:0030215 | semaphorin receptor binding | molecular_function | Binding to a semaphorin receptor. [GOC:ceb, PMID:12001990] |
| GO:0001755 | neural crest cell migration | biological_process | The characteristic movement of cells from the dorsal ridge of the neural tube to a variety of locations in a vertebrate embryo. [GOC:ascb_2009, GOC:dph, GOC:tb, ISBN:0878932437] |
| GO:0071526 | semaphorin-plexin signaling pathway | biological_process | The series of molecular signals generated as a consequence of a semaphorin receptor (composed of a plexin and a neurophilin) binding to a semaphorin ligand. [GOC:BHF, GOC:mah, GOC:vk, PMID:15239959] |
| GO:0048843 | negative regulation of axon extension involved in axon guidance | biological_process | Any process that stops, prevents, or reduces the frequency, rate or extent of axon extension involved in axon guidance. [GOC:devbiol] |
| GO:0007411 | axon guidance | biological_process | The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues. [ISBN:0878932437] |
| GO:0045499 | chemorepellent activity | molecular_function | Providing the environmental signal that initiates the directed movement of a motile cell or organism towards a lower concentration of that signal. [GOC:ai] |
