RAC1

Gene
RAC1
Protein
Rac-like GTP-binding protein 1
Organism
Oryza sativa subsp. japonica
Length
214 amino acids
Function
Small GTPase playing a general role in disease resistance signaling pathway. Acts downstream of heterotrimeric G protein alpha subunit. Regulates cell death and reactive oxygen species production, probably through NADPH oxidase. Also involved in sphingolipid elicitor (SE)-dependent defense signaling. Activates phytoalexin production and alters defense-related genes. Down-regulates metallothionein 2b, a reactive oxygen scavenger (PubMed:10485927, PubMed:11149940, PubMed:12237405, PubMed:15220467). May control lignin synthesis through regulation of both NADPH oxidase and CCR1 activities during defense responses. Stimulates lignin synthesis in suspension cell culture (PubMed:15951489).

Inactive GDP-bound Rho GTPases reside in the cytosol, are found in a complex with Rho GDP-dissociation inhibitors (Rho GDIs), and are released from the GDI protein in order to translocate to membranes upon activation.

Ras-related C3 botulinum toxin substrate 1
Organism
Bos taurus
Length
192 amino acids
Function
Plasma membrane-associated small GTPase which cycles between active GTP-bound and inactive GDP-bound states. In its active state, binds to a variety of effector proteins to regulate cellular responses such as secretory processes, phagocytosis of apoptotic cells, epithelial cell polarization, neurons adhesion, migration and differentiation, and growth-factor induced formation of membrane ruffles. Rac1 p21/rho GDI heterodimer is the active component of the cytosolic factor sigma 1, which is involved in stimulation of the NADPH oxidase activity in macrophages. Essential for the SPATA13-mediated regulation of cell migration and adhesion assembly and disassembly. Stimulates PKN2 kinase activity. In concert with RAB7A, plays a role in regulating the formation of RBs (ruffled borders) in osteoclasts. In podocytes, promotes nuclear shuttling of NR3C2; this modulation is required for a proper kidney functioning. Required for atypical chemokine receptor ACKR2-induced LIMK1-PAK1-dependent phosphorylation of cofilin (CFL1) and for up-regulation of ACKR2 from endosomal compartment to cell membrane, increasing its efficiency in chemokine uptake and degradation (By similarity). In neurons, is involved in dendritic spine formation and synaptic plasticity (By similarity). In synapses, seems to mediate the regulation of F-actin cluster formation performed by SHANK3 (By similarity).

Length

Function
Isoform B has an accelerated GEF-independent GDP/GTP exchange and an impaired GTP hydrolysis, which is restored partially by GTPase-activating proteins. It is able to bind to the GTPase-binding domain of PAK but not full-length PAK in a GTP-dependent manner, suggesting that the insertion does not completely abolish effector interaction.
