Crosstalk has also been shown between GEFs and multiple GTPase signaling pathways. For example, SOS contains a Dbl homology domain in addition to its CDC25 catalytic domain. SOS can act as a GEF to activate Rac1, a RhoGTPase, in addition to its role as a GEF for Ras. SOS is therefore a link between the Ras-Family and Rho-Family GTPase signaling ...
Rap guanine nucleotide exchange factor (GEF) 4 (RAPGEF4), also known as exchange protein directly activated by cAMP 2 (EPAC2) is a protein that in humans is encoded by the RAPGEF4 gene. [ 5 ] [ 6 ] [ 7 ]
Reaction of GeF 4 with fluoride sources produces GeF 5 − anions with octahedral coordination around Ge atom due to polymerization. [6] The structural characterization of a discrete trigonal bipyramidal GeF 5 − anion was achieved by a "naked" fluoride reagent 1,3-bis(2,6-diisopropylphenyl)imidazolium fluoride.
All India Secondary School Examination, commonly known as the class 10th board exam, is a centralized public examination that students in schools affiliated with the Central Board of Secondary Education, primarily in India but also in other Indian-patterned schools affiliated to the CBSE across the world, taken at the end of class 10. The board ...
The inactive form of GTPases (GDP-form) are activated by a class of proteins called Guanosine nucleotide exchange factors (GEFs). GEFs catalyse nucleotide exchange by encouraging the release of GDP from the small GTPase (by displacement of the small GTPase-associated Mg 2+ ion) and GDP's replacement by GTP (which is in at least a 10-fold excess within the cell) .

The large G proteins, for example, are involved in transduction of signaling from the G protein-coupled receptor for a variety of signaling processes like hormonal signaling, [2] and small G proteins are involved in processes like cellular trafficking and cell cycling. [3] GAP's role in this function is to turn the G protein's activity off.
[4] EF-Ts: eEF-1B (β γ) [2] serves as the guanine nucleotide exchange factor for EF-Tu, catalyzing the release of GDP from EF-Tu. [2] EF-G: eEF-2: catalyzes the translocation of the tRNA and mRNA down the ribosome at the end of each round of polypeptide elongation. Causes large conformation changes. [5] EF-P: eIF-5A
