The transcription factor family intimately regulates gene expression in response to hormones, biotic and abiotic factors, symbiotic interactions, cell differentiation, and stress signalling pathways in plants. In this study, 170 AP2/ERF family genes are identified by phylogenetic analysis of the rice genome (Oryza sativa l. japonica) and they are divided into a total of 11 groups, including fou...

It was established previously that the 15-kDa protein phosphorylated in 3T3-L1 adipocytes treated with insulin and phenylarsine oxide is O-phospho-Tyr19 422(aP2) protein, a fatty acid-binding protein. To assess its capacity to serve as substrate of the insulin receptor tyrosine kinase in vitro, native 422(aP2) protein was isolated from 3T3-L1 adipocytes and purified to homogeneity. Receptor-cat...

The Arabidopsis protein AINTEGUMENTA (ANT) is an important regulator of organ growth during flower development. ANT is a member of the AP2 subclass of the AP2/ERF family of plant-specific transcription factors. These proteins contain either one or two copies of a DNA-binding domain called the AP2 domain. Here, it is shown that ANT can act as a transcriptional activator in yeast through binding ...

FUS-DDIT3 is a chimeric oncogene generated by the most common chromosomal translocation t(12;16)(q13;p11) associated to liposarcomas. The application of transgenic methods and the use of primary mesenchymal progenitor cells to the study of this sarcoma-associated FUS-DDIT3 gene fusion have provided insights into their in vivo functions and suggested mechanisms by which lineage selection may be ...

The matrix metalloproteinase gelatinase A plays a central role in several critical physiologic processes, including angiogenesis, tumor invasion/metastasis, and chronic inflammation. We demonstrate that high level gelatinase A expression is mediated by a unique interaction of two developmentally regulated transcription factors, AP2 and YB-1, within a discrete 40-base pair enhancer element (RE-1...

Micro-RNAs are recognized as important posttranscriptional regulators in plants. The relevance of micro-RNAs as regulators of the legume-rhizobia nitrogen-fixing symbiosis is emerging. The objective of this work was to functionally characterize the role of micro-RNA172 (miR172) and its conserved target APETALA2 (AP2) transcription factor in the common bean (Phaseolus vulgaris)-Rhizobium etli sy...

The AP2/ERF transcription factor family is one of the largest families involved in growth and development, hormone responses, and biotic or abiotic stress responses in plants. In this study, 281 AP2/ERF transcription factor unigenes were identified in Chinese cabbage. These superfamily members were classified into three families (AP2, ERF, and RAV). The ERF family was subdivided into the DREB s...

Understanding the biochemical and molecular basis of drought mechanism in rice is important as drought is one of the major causes affecting rice crop adversely. A 1017 bp gene sequence encoding AP2/ERF family TF was isolated from Oryza sativa sp. Indica cv N22 encoding a protein of 338 amino acid residues, with a molecular weight of 36.58 kDa, and no intron in the ORF. The gene was named as AP2...

Endocytic cargo such as the transferrin receptor is incorporated into clathrin-coated pits by associating, via tyrosine-based motifs, with the AP2 complex. Cargo-AP2 interactions occur via the mu2 subunit of AP2, which needs to be phosphorylated for endocytosis to occur. The most likely role for mu2 phosphorylation is in cargo recruitment because mu2 phosphorylation enhances its binding to inte...
