A novel 53-kDa polypeptide from chicken embryo.

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...

P 53 ( Protein 53 kDa )

A novel 53 kDa actin binding protein from porcine brain--further biochemical and immunological characterization.

We have previously described some of the characteristics of an actin binding protein, 53 K protein, purified from porcine brains. The purification procedure was revised in order to investigate of this actin binding protein further. A Scatchard plot analysis showed that the association constant between actin and the 53 K protein has around the same value as those reported for the fascin-actin an...

A novel 29-kDa chicken heat shock protein.

The family of small heat shock proteins is the more variable among the highly conserved superfamily of heat shock proteins (HSP). Using a metabolic labeling procedure with tissue explants, we have detected in chickens a new member of the small HSP family with an apparent molecular weight of 29-kDa. This protein was induced in broiler chickens' heart muscle and lungs following an in vivo heat st...

Nonmyristoylated p60v-src fails to phosphorylate proteins of 115-120 kDa in chicken embryo fibroblasts.

We have used anti-phosphotyrosine antibodies to identify a large number of tyrosine phosphoproteins in Rous sarcoma virus (RSV)-transformed chicken embryo fibroblasts. Most of these proteins were found in the 100,000 X g supernatant when cells were separated into soluble and particulate fractions; however, one group of proteins, of 115-120 kDa, was found in the particulate fraction. The phospho...
