6 Things You Didn’t Know About Proteins

Posted by Provista Diagnostics on December 15, 2016

Protein is in each of the trillions of cells in the human body, making it an essential part of human life


Here are 6 things you didn't know about proteins, that prove just how important they are:

Proteins are essential for cellular function, making them more coplex, diverse, dynamic and reflective of cellular   physiology than genes

number 2- blog22.pngProteins are made using the “central Dogma of Biology,” which states that DNA makes RNA and RNA makes proteins

Proteins control many of the human biological processes, both normal and abnormal.

Proteomic technologies can identify changes in protein expression or patterns of protein signatures in the blood specific to a particular cancer. Proteomic tests detect the presence or absence of cancer in real time.

BRCA1 and BRCA2 are human genes that produce tumor suppressor proteins. These proteins help repair damaged DNA and, therefore, play a role in ensuring the stability of the cell’s genetic material.

55 to 65 percent of women who inherit a harmful BRCA1mutation and around 45 percent of women who inherit a harmful BRCA2 mutation will develop breast cancer by age 70 years


Proteins constantly change as a consequence of disease and therefore provide insight into biological processes associated with cancer development, while also providing real time information on the physical state of patients. This information proves that there is room for protein biomarkers to be used to help improve the accuracy and efficiency of breast cancer detection.
