Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells
FEBS Open Bio, EarlyView.Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

FEBS Open Bio, EarlyView.IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Conformation spaces of proteins
Proteins: Structure, Function, and Bioinformatics, 2001We report a simple method for measuring the accessible conformational space explored by an ensemble of protein structures. The method is useful for diverse ensembles derived from molecular dynamics trajectories, molecular modeling, and molecular structure determinations. It can be used to examine a wide range of time scales.

Conformational spectra — probing protein conformational changes
Biophysical Chemistry, 1999Stafford [Biophys. J. 17 (1996) MP452] has shown that it is possible, using the analytical ultracentrifuge in sedimentation velocity mode, to calculate the molecular weights of proteins with a precision of approximately 5%, by fitting Gaussian distributions to g(s*) profiles so long as partial specific volume and the radial position of the meniscus are

Protein conformational prediction
Trends in Biochemical Sciences, 1989The prediction of the secondary and tertiary structure of globular and membrane proteins is reviewed. Prospects are encouraging for future developments, but present algorithms require cautious interpretation.

Characterizing Intermediate Conformations in Protein Conformational Space
2013In this paper we present a novel parallel coordinate based clustering method using Gaussian mixture distribution models to characterize the conformational space of proteins. We detect highly populated regions which may correspond to intermediate states that are difficult to detect experimentally.

Conformational stability of globular proteins
Trends in Biochemical Sciences, 1990The conformational stability of ribonuclease T1 has been measured as a function of the variables of most interest to biochemists: temperature, pH, salt concentration, disulfide-bond content and amino acid sequence. The results provide insight into the forces that stabilize globular proteins.
