Lipids1
- There are at least six types of lipids including fatty acids, isoprenoids, sterols, phospholipids, glycosylphosphatidylinositol anchors, and lipid-derived electrophiles, which can be covalently attached to proteins ( Chen et al, 2018 ). (life-science-alliance.org)
Computational design of protein1
- Moreover, with advances in the computational design of protein folding and protein-protein interfaces, considerable progress has recently been made in the de novo design of protein assemblies. (springeropen.com)
Distinct1
- These proteins had a high degree of amino acid identity but were determined to be distinct mitogens. (beauty104.com.tw)
Covalently1
- This assembly results in a spontaneous, essentially traceless splicing reaction that covalently links the two flanking protein segments through native chemical ligation 9 . (biorxiv.org)
Myosin1
- NMM2 consists of two myosin heavy chains encoded by MYH9, MYH10, MYH14 (NMHC-IIA, B and C) or MYH11, two copies of MYL6 essential light chain protein, and two regulatory light chains (MRLCs), MYL9 and MYL12B. (reactome.org)
Function3
- This list aims to organize information on how proteins are most often classified: by structure, by function, or by location. (wikipedia.org)
- Proteins may also be classified based on their celluar function. (wikipedia.org)
- Manipulation of proteins by chemical modification is a powerful way to decipher their function or harness that function for therapeutic purposes. (biorxiv.org)
Gene4
- methylation at certain residues of histones can regulate gene expression [ 4 ], and glycosylation is responsible for targeting substrates and changing protein half-life [ 2 ]. (hindawi.com)
- With 35,000 genes and hundreds of thousands of protein states to identify, correlate, and understand, it no longer suffices to rely on studies of one gene, gene product, or process at a time. (genomicglossaries.com)
- One of the few antigens against which mammals develop protective immunity is the highly polymorphic OspC protein, encoded by the ospC gene on the cp26 plasmid. (cdc.gov)
- By means of DNA sequencing of a large sample collection of the pathogen from across the United States, we studied the gene for the bacterium's highly diverse OspC protein, protective immunity against which develops in animals. (cdc.gov)
Regulatory1
- Protein Phosphatase 2A (PP2A) is a widely expressed family of protein phosphatases made of a core dimer, composed of a catalytic (C) subunit and a structural (A) subunit, in association with a third variable regulatory (B) subunit. (ac.be)
Adopt2
- While most proteins adopt a single stable fold, a few proteins can rapidly interconvert between one or more folds. (wikipedia.org)
- Finally other proteins appear not to adopt any stable conformation and are referred to as intrinsically disordered. (wikipedia.org)
