>gnl|CDD|188660 cd08705, RGS_R7-like, Regulator of G protein signaling (RGS) domain
found in the R7 subfamily of proteins. The RGS
(Regulator of G-protein Signaling) domain is an
essential part of the R7 (Neuronal RGS) protein
subfamily of the RGS protein family, a diverse group of
multifunctional proteins that regulate cellular
signaling events downstream of G-protein coupled
receptors (GPCRs). As a major G-protein regulator, RGS
domain containing proteins are involved in many crucial
cellular processes such as regulation of intracellular
trafficking, glial differentiation, embryonic axis
formation, skeletal and muscle development, and cell
migration during early embryogenesis. The R7 subfamily
includes RGS6, RGS7, RGS9, and RGS11, all of which, in
humans, are expressed predominantly in the nervous
system, form an obligatory complex with G-beta-5, and
play important roles in the regulation of crucial
neuronal processes. In addition, R7 proteins were found
to bind many other proteins outside of the G protein
signaling pathways including: m-opioid receptor,
beta-arrestin, alpha-actinin-2, NMDAR, polycystin,
spinophilin, guanylyl cyclase, among others.

>gnl|CDD|239897 cd04450, DEP_RGS7-like, DEP (Dishevelled, Egl-10, and Pleckstrin)
domain found in RGS (regulator of G-protein signaling)
proteins of the subfamily R7. This subgroup contains
RGS7, RGS6, RGS9 and RGS11. They share a common domain
architecture, containing, beside the RGS domain, a DEP
domain and a GGL (G-protein gamma subunit-like )
domain. RGS proteins are GTPase-activating (GAP)
proteins of heterotrimeric G proteins by increasing the
rate of GTP hydrolysis of the alpha subunit. The fungal
homologs, like yeast Sst2, share a related common
domain architecture, containing RGS and DEP domains.
Sst2 has been identified as the principal regulator of
mating pheromone signaling and recently the DEP domain
of Sst2 has been shown to be necessary and sufficient
to mediate receptor interaction.

processes such as vision and motor control.
Additionally they have been implicated in many
neurological conditions such as anxiety, schizophrenia,
and drug dependence. RGS6 exists in multiple splice
isoforms with identical RGS domains, but possess
complete or incomplete GGL domains and distinct N- and
C-terminal domains. RGS6 interacts with SCG10, a
neuronal growth-associated protein and therefore
regulates neuronal differentiation. Another RGS6-binding
protein is DMAP1, a component of the Dnmt1 complex
involved in repression of newly replicated genes.
Mutations of a critical residue required for interaction
of RGS6 protein with G proteins did not affect the
ability of RGS6 to interact with both SCG10 and DMAP1.
As a major G-protein regulator, RGS domain containing
proteins are involved in many crucial cellular processes
such as regulation of intracellular trafficking, glial
differentiation, embryonic axis formation, skeletal and
muscle development, and cell migration during early
embryogenesis.

regulatory roles as GTPase activating proteins (GAPs) of

inactive, G-alpha-subunits bind GDP, which is released
and replaced by GTP upon agonist activation. GTP binding
leads to dissociation of the alpha-subunit and the

effectors molecules and propagate signaling cascades
associated with cellular growth, survival, migration,
and invasion. Deactivation of the G-protein signaling

>gnl|CDD|238929 cd01967, Nitrogenase_MoFe_alpha_like, Nitrogenase_MoFe_alpha_like:
Nitrogenase MoFe protein, alpha subunit_like. The
nitrogenase enzyme catalyzes the ATP-dependent reduction
of dinitrogen to ammonia. Three genetically distinct
types of nitrogenase systems are known to exist: a
molybdenum-dependent nitrogenase (Mo-nitrogenase), a
vanadium dependent nitrogenase (V-nitrogenase), and an
iron-only nitrogenase (Fe-nitrogenase). These
nitrogenase systems consist of component 1 (MoFe
protein, VFe protein or, FeFe protein respectively) and,
component 2 (Fe protein). This group contains the alpha
subunit of component 1 of all three different forms. The
most widespread and best characterized of these systems
is the Mo-nitrogenase. MoFe is an alpha2beta2 tetramer,
the alternative nitrogenases are alpha2beta2delta2
hexamers having alpha and beta subunits similar to the
alpha and beta subunits of MoFe. The role of the delta
subunit is unknown. For MoFe, each alphabeta pair of
subunits contains one P-cluster (located at the
alphabeta interface) and, one molecule of iron
molybdenum cofactor (FeMoco) contained within the alpha
subunit. The Fe protein is a homodimer which contains, a
single [4Fe-4S] cluster from which electrons are
transferred to the P-cluster of the MoFe and in turn,
to FeMoCo the site of substrate reduction. The
V-nitrogenase requires an iron-vanadium cofactor
(FeVco), the iron only-nitrogenase an iron only cofactor
(FeFeco). These cofactors are analogous to the FeMoco.
The V-nitrogenase has P clusters identical to those of
MoFe. In addition to N2, nitrogenase also catalyzes the
reduction of a variety of other substrates such as
acetylene The V-nitrogenase differs from the Mo-
nitrogenase in that it produces free hydrazine, as a
minor product during dinitrogen reduction and, ethane
as a minor product during acetylene reduction.
