EcoRI fragments of DNA isolated from the different mouse organs were hybridized to radioactivity labelled probe specific for the gene of oncoprotein p53. The analysis of the blot-hybridization points to the existence of the specific blockage of an EcoRI site flanking a 3.3 kb fragment of DNA including the pseudogene p53, isolated from the skin tissue. The existence of a polymorphous EcoRI site localized distally to the pseudogene p53 has been demonstrated in the DNA of mice of different lines.

Functionally important amino acid sequences in proteins are often located at multiple sites. Three-dimensional structural analysis and site-directed mutagenesis may be performed to allocate functional sites for understanding structure‒function relationships and for developing novel inhibitory drugs. However, such methods are too demanding to comprehensively cover potential functional sites throughout a protein chain.

The conventional polymerase chain reaction (PCR) methods are time-consuming and dependent on laboratory equipment. Recombinase-aided amplification (RAA) is a rapid, specific, sensitive, and cost-effective isothermal nucleic acid amplification technique.

SNPs could either cause a disorder or directly alter the efficacy of a particular treatment and act as biological markers. The SNP rs7587633 C/T present in the intronic region of the gene has been studied for its role in psoriasis vulgaris and Palmoplantar pustulosis. To genotype rs7587633 C/T using PCR-RFLP no restriction site is present for any of the restriction enzymes at the SNP position.
