An assessment of feature relevance in predicting protein function from sequence [PDF]

, 2004
Improving the performance of protein function prediction is the ultimate goal for a bioinformatician working in functional genomics. The classical prediction approach is to employ pairwise sequence alignments. However this method often faces difficulties

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

CHAPTER 1.1. Disulfide Bonds in Protein Folding and Stability [PDF]

, 2018
Disulfide bonds are unique among post-translational modifications, as they add covalent crosslinks to the polypeptide chain. Accordingly, they can exert pronounced effects on protein folding and stability. This is of particular importance for secreted or

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Inferring function using patterns of native disorder in proteins [PDF]

, 2007
Natively unstructured regions are a common feature of eukaryotic proteomes. Between 30% and 60% of proteins are predicted to contain long stretches of disordered residues, and not only have many of these regions been confirmed experimentally, but they ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Epigenetic activation of secretory phenotypes in senescence by the FOXQ1-SIRT4-GDH signaling

Cell Death and Disease, 2023
Although metabolic reprogramming is characterized as a hallmark of aging, implications of the crucial glutamate dehydrogenase (GDH) in human senescence remain poorly understood.

Structure and function of proteins

Bioscience Reports, 1988
It is now many years since Linderstr6m-Lang suggested that the threedimensional conformation of a protein is the end result of its primary, secondary and tertiary structures. The protein's primary structure is represented by its amino acid sequence and the secondary structure by its tr-helices and E-sheets; its final three-dimensional conformation is ...

Exploring Protein Sequence Space Using Computationally Directed Recombination [PDF]

, 2006
Evolution has provided us with many protein sequences. However, these sequences represent a very small fraction of the possible sequences. In the laboratory, scientists have explored areas of sequence space not represented by natural proteins both to ...
