2021年2月8日 · QWRF1 (also named SNOWY COTYLEDON3, SCO3) is a peroxisome-associated protein required for plastid development. Its localization to the periphery of peroxisomes is dependent on microtubules (Albrecht et al., 2010). So far, there have been no reports about the function of QWRF2 in Arabidopsis.

2021年2月9日 · Our results suggest that QWRF1 and QWRF2 are likely microtubule-associated proteins with functional redundancy in fertility and floral organ development, which probably exert their effects via...

2021年2月9日 · QWRF1 and QWRF2 display similar expression patterns and are both localized to microtubules in vitro and in vivo. Furthermore, we found altered cortical microtubule organization and arrangements in qwrf1qwrf2 cells, consistent with abnormal cell expansion in different floral organs, which eventually led to poor fertility.

QWRF family; AUG8 belongs to the plant QWRF motif-containing protein family, which also includes microtubule-associated protein ENDOSPERM DEFECTIVE 1 and SNOWY COTYLEDON 3. AUG8 binds the microtubule plus-end and participates in the reorientation of microtubules in hypocotyls (the stem of a germinating seedling).

2024年9月18日 · QWRF motif protein (DUF566) GeneRIFs: Gene References Into Functions. EDE1, but not AUG8, is associated with acentrosomal spindle and phragmoplast microtubule (MT) arrays in patterns indistinguishable from those of the AUG1-7 subunits and the gamma-tubulin complex proteins (GCPs) that exhibit biased localization toward MT minus ends.

QWRF1 or QWRF2 protein was, respectively, incubated with or without paclitaxel-stabilized pre-polymerized microtubules before high-speed centrifugation. Both QWRF1 and QWRF2 were co-sedimented...

By searching the Gramene database, we revealed a gene with ID Zm00001d028073 that encoded a QWRF homolog protein in maize. We cloned the CDS of this gene into an overexpression vector, pBCXUN, driven by the maize UBI promoter, and introduced it into the maize inbred line B73-329 using Agrobacterium-mediated transformation.

Showing features for region, compositional bias, motif. Belongs to the QWRF family. Search… This entry describes 2 isoforms produced by Alternative splicing. This isoform has been chosen as the canonical sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

2021年2月9日 · Arabidopsis QWRF family proteins share a highly conserved QWRF amino acid sequence and a DUF566 domain of unknown function (Pignocchi et al., 2009; Albrecht et al., 2010). One member of this family, ENDOSPERMDEFECTIVE1 (EDE1, also named QWRF5), has been shown to be an essential MAP for endosperm development ( Pignocchi et al., 2009 ).

Controls stem cell fate via the transcription regulation of WUS in the shoot apical meristem, by modulating its promoter. LFY-dependent repressor of the meristem identity switch from vegetative to reproductive development probably by modulating chromatin state.
