2022年9月7日 · Auxin-binding protein 1 (ABP1) is an auxin receptor that, in complex with transmembrane kinase 1 (TMK1), has a key role in the auxin-induced global phosphorylation of proteins and...

2021年12月1日 · The auxin-binding protein 1 (ABP1) has endured a history of undulating prominence as a candidate receptor for this important phytohormone.

AUXIN BINDING PROTEIN 1 (ABP1) has long been proposed as an auxin receptor to regulate cell expansion. The embryo lethality of ABP1-null mutants demonstrates its fundamental role in plant development, but also hinders investigation of its involvement in post-embryonic processes and its mode of action.

2023年11月17日 · Auxin-binding protein 1 (ABP1) physically interacts with quintessential transmembrane kinases (TMKs) and was proposed to act as an extracellular auxin receptor, but its role was disputed because abp1 knockout mutants lack obvious morphological phenotypes.

2010年8月1日 · ABP1 is involved in a broad range of cellular responses to auxin, acting either as the main regulator of the response, such as seen for entry into cell division or, as a fine-tuning device as for the regulation of expression of early auxin response genes.

These findings show that TMK proteins and ABP1 form a cell surface auxin perception complex that activates ROP signaling pathways, regulating nontranscriptional cytoplasmic responses and associated fundamental processes.

2015年3月2日 · Which role is played by ABP1 in the ER, how the ABP1 signaling diverges for its different effects, and how the ABP1 arrives at the apoplast are still open questions. These unanswered issues are just a few examples that have yet …

Auxin-binding protein 1 (ABP1) is an auxin receptor for responses not primarily regulated by gene regulation. One fast response is protoplast swelling. By using immunological ABP1 tools we showed that the highly conserved box a is not alone important for auxin binding.

Whether auxin-binding protein 1 (ABP1) is an auxin receptor has been a source of debate for decades 1,4. Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds auxin specifically at an acidic pH that is typical of the apoplast.

2011年6月29日 · AUXIN BINDING PROTEIN 1 (ABP1) has long been proposed as an auxin receptor to regulate cell expansion. The embryo lethality of ABP1-null mutants demonstrates its fundamental role in plant development, but also hinders investigation of its involvement in post-embryonic processes and its mode of action.
