P 53 ( Protein 53 kDa )

Protein Description 393 amino acids; 53 kDa phosphoprotein; contains, from N-term to C-term, a transactivation domain, a DNA-binding domain, nuclear localization signals and a tetramerization domain. Expression Widely expressed. Localisation Nucleus. Function Tumour suppressor gene; P53 is a transcriptional regulator acting as a guardian of the genome; in response to DNA damage, p53 is overexpr...

Tauri stars rotate differentially ?

We compute the rotation profile of a T Tauri star from the balance between the different components of the Reynolds stress and the meridional circulation. We first use a simple model to study the influence of the meridional flow on the differential rotation and vice versa. A more realistic model is then presented, which includes the stratification of the turbulence derived from a stellar model....

A comparative high-resolution spectroscopic study of the Hyades giants γ Tauri and Tauri

Spectra of the Hyades K0 giants γ Tau and Tau in the regions 5852–5864 Å and 6145–6176 Å have been recorded at high resolution and with signal/noise in the range 150–250. A critical comparison reveals that, although nearly all lines in the observed regions have a similar depth, lines of Tau are broader by about 10% than those of γ Tau. An LTE analysis indicates that slightly higher turbulent br...
