unusual facts about Protein S


Protein S

In the circulation, Protein S exists in two forms: a free form and a complex form bound to complement protein C4b-binding protein (C4BP).

50S

The model of Hm 50S determined in 2000 by Nenad Ban and colleagues in the laboratory of Thomas Steitz includes 2711 of the 2923 nucleotides of 23S rRNA, all 122 nucleotides of its 5S rRNA, and structure of 27 of its 31 proteins.

Bombinin

In molecular biology, the bombinin family of antimicrobial peptides includes the bombinin and maximin proteins from Bombina maxima (Giant fire-bellied toad).

Carboxypeptidase A inhibitor

The N-terminal region and the mature inhibitor are weakly related to other solananaceous proteins found in this family, from potato, tomato and henbane, which have been incorrectly described as metallocarboxypeptidase inhibitors.

Dehydroepiandrosterone

Finally, DHEA is thought to regulate a handful of other proteins via indirect, genomic mechanisms, including the enzymes P4502C11 and 11β-HSD1—the latter of which is essential for the biosynthesis of the glucocorticoids such as cortisol and has been suggested to be involved in the antiglucocorticoid effects of DHEA—and the carrier IGFBP1.

Dialysis tubing

In the context of life science research, dialysis tubing is typically used in the sample clean-up and processing of proteins and DNA samples or complex biological samples such as blood or serum.

Hydroxyl

When biological systems are exposed to hydroxyl radicals, they can cause damage to cells, including those in humans, where they react with DNA, lipids, and proteins.

Kringle

The shape of the kringle has given name to a similarly entangled feature found in some proteins, the so-called Kringle domain.

LCCL domain

In molecular biology, the LCCL domain is a protein domain which has been named after several well-characterised proteins that were found to contain it, namely Limulus clotting factor C, Coch-5b2 (Cochlin) and Lgl1.

Parthenium argentatum

While Hevea-derived rubber contains proteins that can cause severe allergic reactions in a few people, guayule does not.

Protein sparing

Bodybuilding and other strength training promotes the utilization and conservation of protein's amino acids in the body.

RNA of unknown function

The same convention is used for proteins, they can be named domains of unknown function (DUFs).

Robijn Bruinsma

His research specialties include the numerical Simulation of active proteins and of Gene transcription, the self-assembly of viruses, DNA, and chromatin, the electrostatics of DNA and electrical transport along DNA, and adhesion of vesicles and cells.

STAT5

Signal Transducer and Activator of Transcription 5 refers to two highly related proteins, STAT5A and STAT5B, which are part of the seven-membered STAT family of proteins.

Sterol regulatory element-binding protein

In addition to S1P and S2P, the regulated release of transcriptionally active SREBP requires the cholesterol-sensing protein SREBP cleavage activating protein (Scap), which forms a complex with SREBP owing to interaction between their respective carboxy-terminal domains.

Suprapedal gland

For example in the suprapedal gland of the land snail Pomatias elegans there are three types of gland cells: cells producing mucoproteins, cells producing proteins and cells producing sulphated mucopolysaccharides.

Syntrophin

The syntrophins are a family of five 60-kiloDalton proteins that are associated with dystrophin, the protein associated with Duchenne muscular dystrophy and Becker muscular dystrophy.

TAL effector

TAL (transcription activator-like) effectors (often referred to as TALEs but not to be confused with the three amino acid loop extension family of proteins) are proteins secreted by Xanthomonas bacteria via their type III secretion system when they infect various plant species.

Zona pellucida

In the mouse (the best characterised mammalian system), the zona glycoprotein, ZP3, is responsible for sperm binding, adhering to proteins on the sperm plasma membrane (GalT).
