Descriptions

ARHGEF11 belongs to a small family of RhoA-specific nucleotide exchange factors that mediates signaling through select G-protein-coupled receptors via Gα12/13 and activates RhoA by catalyzing the exchange of GDP to GTP. ARHGEF11 is a multidomain protein composed of PDZ, regulators of G-protein signaling-like (RGSL), Dbl-homology (DH), and pleckstrin-homology (PH) domains. The autoinhibitory activity resides in the 672-712 fragment in such a way that it disturbs the catalytically competent conformation of the GEF switch. The intrinsically disordered L2 linker located between RGSL domain and DH domain occupied the RhoA-binding site on DH domain, thereby suppressing the DH domain. In addition, ARHGEF12 removed RGSL domain showed partial relief of autoinhibition, suggesting that RGSL domain supports autoinhibition indirectly.

2 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
membrane A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.

3 GO annotations of molecular function

Name Definition
G protein-coupled receptor binding Binding to a G protein-coupled receptor.
GTPase activator activity Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
guanyl-nucleotide exchange factor activity Stimulates the exchange of GDP to GTP on a signaling GTPase, changing its conformation to its active form. Guanine nucleotide exchange factors (GEFs) act by stimulating the release of guanosine diphosphate (GDP) to allow binding of guanosine triphosphate (GTP), which is more abundant in the cell under normal cellular physiological conditions.

4 GO annotations of biological process

Name Definition
G protein-coupled receptor signaling pathway The series of molecular signals initiated by a ligand binding to its receptor, in which the activated receptor promotes the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, and ends with regulation of a downstream cellular process. The pathway can start from the plasma membrane, Golgi or nuclear membrane.
positive regulation of DNA-templated transcription Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.
positive regulation of L-glutamate import across plasma membrane Any process that activates or increases the frequency, rate or extent of L-glutamate import into a cell.
Rho protein signal transduction The series of molecular signals within the cell that are mediated by a member of the Rho family of proteins switching to a GTP-bound active state.
