first time we have identified the -100/+41 to -70/+41 bp core promoter regions of Swiprosin-1 gene, and showed ADR1 and Sp1 are important transcription factors that directly bind to and transactivate the Swiprosin-1 promoter region.

EFHD2 was identified as expressed in highly metastatic tumor cells. EFHD2 increased the formation of protrusive invadopodia structures and cell migration and invasion abilities and promoted the epithelial-to-mesenchymal transition (EMT) character of lung adenocarcinoma cells. We demonstrated that the mechanism of EFHD2 in enhancing EMT occurs partly through inhibition of caveolin-1 (CAV1) for cancer progression.

Data demonstrate that EFhd2 shows unique structural and biological features as an EF-hand containing F-actin bundling protein. For F-actin bundling activity, structural stabilization of the EF-hand domains was found to occur in the presence of Ca2+. The core region of EFhd2 maintains its structure in the absence of Ca2+ ; however, changes in local conformational flexibility reduce F-actin bundling activity of EFhd2.
Title: Structural implications of Ca(2+)-dependent actin-bundling function of human EFhd2/Swiprosin-1.
Phosphorylation at Ser183 of EFhd2 causes changes in the local conformational dynamics and the surface charge distribution of the actin-binding site, resulting in a re-coordination of the actin-binding sites in the dimer structure.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
