FUS/TLS was initially identified as a fusion protein (FUS-CHOP) produced as a result of chromosomal translocations in human cancers, especially liposarcomas. [6] [9] In these instances, the promoter and N-terminal part of FUS/TLS is translocated to the C-terminal domain of various DNA-binding transcription factors (e.g. CHOP) conferring a strong transcriptional activation domain onto the ...
Lymphotoxin-alpha (LT-α) formerly known as tumor necrosis factor-beta (TNF-β) [5] [6] is a protein that in humans is encoded by the LTA gene. [7] [8] Belonging to the hematopoietic cell line, LT-α exhibits anti-proliferative activity and causes the cellular destruction of tumor cell lines. [7]
This secondary structure then folds to produce the tertiary structure of the protein. The tertiary structure is the proteins overall 3D structure which is made of different secondary structures folding together. In the tertiary structure, key protein features e.g. the active site, are folded and formed enabling the protein to function.
In molecular biology and genetics, transcriptional regulation is the means by which a cell regulates the conversion of DNA to RNA (transcription), thereby orchestrating gene activity. A single gene can be regulated in a range of ways, from altering the number of copies of RNA that are transcribed, to the temporal control of when the gene is ...
In TLS, the breakdown occurs after cytotoxic therapy or from cancers with high cell turnover and tumor proliferation rates. [4] The metabolic abnormalities seen in tumor lysis syndrome can ultimately result in serious complications such as acute uric acid nephropathy , acute kidney failure , seizures , cardiac arrhythmias , and death.
Amino acid activation (also known as aminoacylation or tRNA charging) refers to the attachment of an amino acid to its respective transfer RNA (tRNA). The reaction occurs in the cell cytosol and consists of two steps: first, the enzyme aminoacyl tRNA synthetase catalyzes the binding of adenosine triphosphate (ATP) to a corresponding amino acid, forming a reactive aminoacyl adenylate ...
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
There is also now a crystal structure of the monomeric, inactive Apaf-1 subunit (PDB 3SFZ). [1] [3] Once formed, the apoptosome can then recruit and activate the inactive pro-caspase-9. Once activated, this initiator caspase can then activate effector caspases and trigger a cascade of events leading to apoptosis.
