P53 (protein 53 kDa)

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...

Tumor Protein 53-Induced Nuclear Protein 1 Enhances p53 Function and Represses Tumorigenesis

Tumor protein 53-induced nuclear protein 1 (TP53INP1) is a stress-induced p53-target gene whose expression is modulated by transcription factors such as p53, p73, and E2F1. TP53INP1 gene encodes two isoforms of TP53INP1 proteins, TP53INP1α and TP53INP1β, both of which appear to be key elements in p53 function. In association with homeodomain-interacting protein kinase-2 (HIPK2), TP53INP1 phosph...

Protective effect of recombinant Trichinella 53-kDa protein in sepsis and the effect on macrophages

The survival rate of the recombinant Trichinella 53-kDa protein infected by the cecal ligation and puncture (CLP) model of sepsis in rats and the expression difference of macrophages were analyzed. Eighteen clean SD rats were selected for the present study. The rats were divided into the sham operation (n=5), control (n=5) and experimental (n=8) groups. The rats in the sham operation group unde...
