The isoforms of the p53 protein
WebOct 24, 2024 · TGF-β signaling plays a pivotal role in promoting tumor cell migration and cancer metastasis. ΔNp63α and TAp63α are two major isoforms of p53-related p63 protein. Our recent study has shown that TGF-β1 promotes ΔNp63α protein degradation to facilitate cancer metastasis.

WebAbstract. p53 is a transcription factor with a key role in the maintenance of genetic stability and therefore preventing cancer formation. It belongs to a family of genes composed of p53, p63, and p73.The p63 and p73 genes have a dual gene structure with an internal promoter in intron-3 and together with alternative splicing, can express 6 and 29 mRNA variants, … WebJan 13, 2024 · p53 gene family members in humans and other organisms encode a large number of protein isoforms whose functions are largely undefined. Using Drosophila as a model, we find that a p53B isoform is expressed predominantly in the germline where it colocalizes with p53A into subnuclear bodies. It is only p53A, however, that mediates the …
WebApr 15, 2024 · The p53 isoform Δ133p53β is known to be associated with cancers driven by inflammation. Many of the features associated with the development of inflammation in rheumatoid arthritis (RA) parallel those evident in cancer progression. However, the role of this isoform in RA has not yet been explored. The aim of this study was to determine … Web(A) Visualization of p53 protein levels through chemiluminescence western blot detection then ponceau staining.

WebThe C-terminal p53 isoform p53b is produced by an alternative splicing in intron 9, leading to the replacement of the OD by 10 new residues. The N-terminal p53 isoform D133p53 is encoded by a transcript initiated in intron 4 and lacks the TAD, PXXP, and part of the DBD. The Dp53 protein isoform is generated by a noncanonical alternative splicing WebJun 25, 2012 · The p53 protein isoforms can be categorized into four subclasses: TAp53, Δ40p53, Δ133p53 and Δ160p53 protein isoforms. Each subclass is composed of the three isoforms α, β and γ.
