The p53 upregulated modulator of apoptosis (PUMA) also known as Bcl-2-binding component 3 (BBC3), is a pro-apoptotic protein, member of the Bcl-2 protein family. [ 5 ] [ 6 ] In humans, the Bcl-2-binding component 3 protein is encoded by the BBC3 gene .
p53, also known as Tumor protein P53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory protein that is often mutated in human cancers. The p53 proteins (originally thought to be, and often spoken of as, a single protein) are crucial in vertebrates , where they prevent cancer formation. [ 5 ]
While apoptosis is required for natural body function, mutations of the apoptosome pathway cause catastrophic effects and changes in the body. Mutations of the cell pathway can either promote cell death or disallow cell death creating a huge amount of disease in the body.
P53, a transcription factor, can bind two sites within the human TIGAR gene to activate expression. [9] [13] One site is found within the first intron, and binds p53 with high affinity. [9] [13] The second is found just prior to the first exon, binds p53 with low affinity, [9] [13] and is conserved between mice and humans. [9]
When there is too much damage, apoptosis is triggered in order to protect the organism from potentially harmful cells.7 p53, also known as a tumor suppressor gene, is a major regulatory protein in the DNA damage response system which binds directly to the promoters of its target genes. p53 acts primarily at the G1 checkpoint (controlling the G1 ...

Unlike necrosis, apoptosis produces cell fragments called apoptotic bodies that phagocytes are able to engulf and remove before the contents of the cell can spill out onto surrounding cells and cause damage to them. [5] Because apoptosis cannot stop once it has begun, it is a highly regulated process.
Disappointed with the outcome and felt we were one of the 12 best teams in the country. We had an extremely challenging schedule and recognize there were two games in particular that we did not ...
