What's a GeneRIF?

Results suggest that ARC3 directly inhibits Z-ring assembly through interaction with FtsZ2 in heteropolymers and that ARC3 activity is spatially regulated by MinD1 and MinE1 to permit Z-ring assembly at the mid-plastid.
Title: Chloroplast division protein ARC3 regulates chloroplast FtsZ-ring assembly and positioning in arabidopsis through interaction with FtsZ2.
In the cotyledons, floral organs, and root columella, the plastid size in the atminE1 mutant was significantly larger than in the wild type, while the plastid number per cell in atminE1 appeared to be inversely smaller than that in the wild type.
Title: Involvement of AtMinE1 in plastid morphogenesis in various tissues of Arabidopsis thaliana.
The chloroplast division site placement involves a balance between the opposing activities of AtMinE1 and AtMinD1, which acts to prevent FtsZ ring formation anywhere outside of the mid-chloroplast.
Title: The assembly of the FtsZ ring at the mid-chloroplast division site depends on a balance between the activities of AtMinE1 and ARC11/AtMinD1.
Data support the model that MinE1 plays a pivotal role in selection of the plastid division site.
Title: Interdependency of formation and localisation of the Min complex controls symmetric plastid division.
MinE1 stimulates MinD1-mediated ATP hydrolysis, but in contrast to prokaryotes, stimulation occurs in the absence of membrane lipids
Title: The plastid division protein AtMinD1 is a Ca2+-ATPase stimulated by AtMinE1.
