Elongation factor 1 alpha (EF1 alpha) is an abundant protein that binds aminoacyl-tRNA and ribosomes in a GTP-dependent manner. EF1 alpha also interacts with the cytoskeleton by binding and bundling actin filaments and microtubules. In this report, the effect of purified EF1 alpha on actin polymerization and depolymerization is examined. At molar ratios present in the cytosol, EF1 alpha signifi...
Intron I of the rat osteocalcin gene contains silencer elements that suppress osteocalcin-reporter fusion gene transcription. The consensus sequence for the transcription factor EF1 is homologous to two pyrimidine-rich repeats in intron 1 that contribute to silencing of osteocalcin-reporter fusion genes. To assess if overexpression of EF1 augments transcriptional repression by these sequences, ...
The probiotic Enterococcus faecium HDRsEf1 (Ef1) has been shown to have positive effects on piglet diarrhoea, but the mechanism has not yet been elucidated. In this study, using the IPEC-J2 cell line to mimic intestinal epithelial cells and enterotoxigenic Escherichia coli (ETEC) K88ac as a representative intestinal pathogen, the mechanism underlying Ef1 protection against an enteropathogen was...
Gene expression of reproductive system of the black tiger shrimp (Peneaus monodon) has been widely studied to address poor maturation problem in captivity. However, a systematic evaluation of reference genes in quantitative real-time PCR (qPCR) for P. monodon reproductive organs is lacking. In this study, the stability of four potential reference genes (18s rRNA, GAPDH, β-actin, and EF1-α) was ...
Overexpression of elongation factor-1 alpha (EF1 alpha) mRNA has been correlated with increased metastatic potential in mammary adenocarcinoma; however, this relationship was not explored at the level of protein expression. As EF1 alpha has been shown in other cell types to be a component of the actin cytoskeleton, a likely effector in metastasis, the actin binding activity of EF1 alpha from me...
Peptides with cell attachment activity are beneficial component of biomaterials for tissue engineering. Conformational structure is one of the important factors for the biological activities. The EF1 peptide (DYATLQLQEGRLHFMFDLG) derived from laminin promotes cell spreading and cell attachment activity mediated by α2β1 integrin. Although the sequence of the EF2 peptide (DFATVQLRNGFPYFSYDLG) is ...
The targeting of mRNA and local protein synthesis is important for the generation and maintenance of cell polarity. As part of the translational machinery as well as an actin/ microtubule-binding protein, elongation factor 1 (EF1 ) is a candidate linker between the protein translation apparatus and the cytoskeleton. We demonstrate in this work that EF1 colocalizes with -actin mRNA and F-actin i...
Indian hedgehog (Ihh) regulates proliferation and differentiation of chondrocytes in the growth plate. Although the biology of Ihh is currently well documented, its transcriptional regulation is poorly understood. delta-EF1 is a two-handed zinc finger/homeodomain transcriptional repressor. Targeted inactivation of mouse delta-EF1 leads to skeletal abnormalities including disorganized growth pla...
ing logical rules should be justified and based on the data that we can observe from a real system. In other words, if a logical rule is abstracted, the input data for the abstracted logical rule should be observable in the real system, and its output data also should be comparable to the observable results of the real system. An abstracted model does not provide more I/O data than the original...
Hb J-Iran [beta77(EF1)His-Asp] is a rare hemoglobin variant, described first in Iran by Rahbar et al. in 1967 . To date, several abnormal hemoglobins have been described from different regions of Turkey . In Turkey, the first Hb J-Iran [beta77(EF1) His-Asp] case was reported by Arcasoy et al. . There are four reported cases from the Turkish population, mostly from our group. These reported case...
