What's a GeneRIF?

Immunolocalization of the cytokinesis-specific syntaxin KNOLLE (KN) in ap1m2 showed that KN was mislocalized and aggregated around the division plane.
Title: The AP-1 μ adaptin is required for KNOLLE localization at the cell plate to mediate cytokinesis in Arabidopsis.
Two distinct types of KNOLLE complexes appear to jointly mediate membrane fusion in Arabidopsis cytokinesis.
Title: SNARE complexes of different composition jointly mediate membrane fusion in Arabidopsis cytokinesis.
KEULE interacted with an open conformation of KNOLLE that complemented both knolle and keule mutants. This interaction occurred at the cell division plane and required the KNOLLE linker sequence between helix Hc and SNARE domain.
Title: Sec1/Munc18 protein stabilizes fusion-competent syntaxin for membrane fusion in Arabidopsis cytokinesis.
KNOLLE regions are necessary for syntaxin function in cytokinesis.
Title: Functional anatomy of the Arabidopsis cytokinesis-specific syntaxin KNOLLE.
Restriction of lateral diffusion by endocytosis may serve to maintain specificity of syntaxin localization during late cytokinesis.
Title: Endocytosis restricts Arabidopsis KNOLLE syntaxin to the cell division plane during late cytokinesis.
Our results suggest that a pair of structurally related myb3r1 myb3r4 transcription factors may positively regulate cytokinesis mainly through transcriptional activation of the KN gene.
Title: R1R2R3-Myb proteins positively regulate cytokinesis through activation of KNOLLE transcription in Arabidopsis thaliana.
