TopPIC (Top-down mass spectrometr/y-based Proteoform Identification and Characterization) identifies and characterizes proteoforms at the proteome level by searching top-down tandem mass spectra against a protein sequence database. TopPIC is a successor to MS-Align+.
Mascot is a software search engine that uses mass spectrometry data to identify proteins from peptide sequence databases. [1] [2] Mascot is widely used by research facilities around the world.
The depth of the plasma proteome encompasses a dynamic range of more than 10 10 between the highest abundant protein (albumin) and the lowest (some cytokines) and is thought to be one of the main challenges for proteomics. [81] Temporal and spatial dynamics further complicate the study of human plasma proteome.
The research underpinning the start of the exploration of the whole human proteome in the Human Protein Atlas program was carried out in the late 1990s and early 2000s. A pilot study employing an affinity proteomics strategy using affinity-purified antibodies raised against recombinant human protein fragments was carried out for a chromosome ...
The term "metabolome" was first used in 1998 [1] [4] and was likely coined to match with existing biological terms referring to the complete set of genes (the genome), the complete set of proteins (the proteome) and the complete set of transcripts (the transcriptome). The first book on metabolomics was published in 2003. [5]
SH2 domains are not present in yeast and appear at the boundary between protozoa and animalia in organisms such as the social amoeba Dictyostelium discoideum. [12]A detailed bioinformatic examination of SH2 domains of human and mouse reveals 120 SH2 domains contained within 115 proteins encoded by the human genome, [13] representing a rapid rate of evolutionary expansion among the SH2 domains.
The discovery of the Wee1 gene is accredited to Paul Nurse, who first identified it in fission yeast (Schizosaccharomyces pombe) in 1978. In his initial experiments, Nurse demonstrated Wee1 to be a negative regulator of mitosis, such that Wee1+ activity was critical in preventing premature mitosis in Cdc25+ (a mitotic inducer) yeast cells and increased Wee1+ expression could further delay cell ...
A manual transmission is only available on rear-wheel drive models. [67] [68] BMW announced the launch of the first-ever M3 Touring in June 2022. Codenamed G81, it will be available along the sedan G80, the coupé M4 G82 and convertible M4 G83. [69] The M3 is powered by the 3.0 L (183 cu in) BMW S58 straight-six engine that debuted in the G01 ...
