Spectral Analysis of Sequence Variability in Basic-Helix-loop-helix (bHLH) Protein Domains

open access: yesEvolutionary Bioinformatics, 2006
The basic helix-loop-helix (bHLH) family of transcription factors is used as a paradigm to explore structural implications of periodicity patterns in amino acid sequence variability.

Incorporating background frequency improves entropy-based residue conservation measures

open access: yesBMC Bioinformatics, 2006
Background Several entropy-based methods have been developed for scoring sequence conservation in protein multiple sequence alignments. High scoring amino acid positions may correlate with structurally or functionally important residues.

The nucleotide and partial amino acid sequences of rat fetuin [PDF]

open access: yes, 1992
Fetuins are among the major plasma proteins, yet their biological role has remained elusive. Here we report the molecular cloning of rat fetuin and the sequence analysis of a full-length clone, RF619 of 1456 bp with an open reading frame of 1056 bp ...

Brucella NyxA and NyxB dimerization enhances effector function during infection

open access: yesFEBS Letters, EarlyView.
Brucella abortus thrives inside cells thanks to the translocation of effector proteins that fine‐tune cellular functions. NyxA and NyxB are two effectors that destabilize the nucleolar localization of their host target, SENP3. We show that the Nyx proteins directly interact with each other and that their dimerization is essential for their function ...

Amino acid sequence of rabbit apolipoprotein E.

open access: yesJournal of Lipid Research, 1991
The complete amino acid sequence of rabbit apolipoprotein E (apoE) was determined by generating three sets of peptides using cyanogen bromide, endoproteinase AspN, and Staphylococcus aureus V8 protease to cleave the protein.

SEQUENCE SIMILARITY BETWEEN THYROID SELF-PROTEIN AND HEPATITIS C VIRUS POLYPROTEIN: possible triggering mechanism of autoimmune thyroiditis

open access: yesArquivos de Gastroenterologia
Background - Exposure to viral antigens that share amino acid sequence similar with self- antigens might trigger autoimmune diseases in genetically predisposed individuals, and the molecular mimicry theory suggests that epitope mimicry between the virus ...

Protein sequence alignment with family-specific amino acid similarity matrices

open access: yesBMC Research Notes, 2011
Background Alignment of amino acid sequences by means of dynamic programming is a cornerstone sequence comparison method. The quality of alignments produced by dynamic programming critically depends on the choice of the alignment scoring function ...

Sequence homology between RNAs encoding rat α-fetoprotein and rat serum albumin [PDF]

open access: yes, 1981
We have determined the sequences of the recombinant DNA inserts of three bacterial plasmid cDNA clones containing most of the rat α-fetoprotein mRNA. The resultant nucleotide sequence of α-fetoprotein was exhaustively compared to the nucleotide sequence ...

Amino Acid Sequence of Endothiapepsin [PDF]

open access: yesEuropean Journal of Biochemistry, 1987
The amino acid sequence of endothiapepsin, the aspartic protease from Endothia parasitica has been determined. The enzyme consists of 330 residues. The sequence determination was performed exclusively at the protein level. The homology of this fungal milk-clotting enzyme with aspartic proteases is demonstrated by alignment with pepsin, chymosin ...

Disruption of SETD3‐mediated histidine‐73 methylation by the BWCFF‐associated β‐actin G74S mutation

open access: yesFEBS Letters, EarlyView.
The β‐actin G74S mutation causes altered interaction of actin with SETD3, reducing histidine‐73 methylation efficiency and forming two distinct actin variants. The variable ratio of these variants across cell types and developmental stages contributes to tissue‐specific phenotypical changes. This imbalance may impair actin dynamics and mechanosensitive
