EOG83XXH8 GO:0017112 1/79 Rab guanyl-nucleotide exchange factor activity molecular_function "Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rab family. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase." [GOC:mah] EOG83XXH8 GO:0032313 1/79 regulation of GTPase activity biological_process "Any process that modulates the rate of GTP hydrolysis by a GTPase." [GOC:jl, GOC:mah] EOG83XXH8 GO:0035011 1/79 melanotic encapsulation of foreign target biological_process "Formation of a multilayered, melanized sheath of cells around a foreign invader." [GOC:bf] EOG83XXH8 GO:0032483 1/79 regulation of Rab protein signal transduction biological_process "Any process that modulates the frequency, rate or extent of Rab protein signal transduction."
