Comprehensive analysis of human protein N-termini enables assessment of various protein forms

Scientific Reports, 2017
Various forms of protein (proteoforms) are generated by genetic variations, alternative splicing, alternative translation initiation, co- or post-translational modification and proteolysis.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Regulation of plant immune receptor accumulation through translational repression by a glycine-tyrosine-phenylalanine (GYF) domain protein

eLife, 2017
Plant immunity is tightly regulated to ensure proper defense against surrounding microbial pathogens without triggering autoimmunity, which negatively impacts plant growth and development.

Post-translational processing of Schizosaccharomyces pombe YPT5 protein. In vitro and in vivo analysis of processing mutants.

Journal of Biological Chemistry, 1993
SpYPT5p is a member of the rab/YPT small GTP-binding protein family, which is believed to be involved in the regulation of intracellular trafficking. The protein sequence terminates with a CXC motif, and in our previous report (Newman, C. M. H., Giannakouros, T., Hancock, J. F., Fawell, E. H., Armstrong, J., and Magee, A. I. (1992) J. Biol. Chem.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Xp54 and related (DDX6-like) RNA helicases : roles in messenger RNP assembly, translation regulation and RNA degradation [PDF]

, 2006
The DEAD-box RNA helicase Xp54 is an integral component of the messenger ribonucleoprotein (mRNP) particles of Xenopus oocytes. In oocytes, several abundant proteins bind pre-mRNA transcripts to modulate nuclear export, RNA stability and translational ...

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

The synthesis and processing of pea legumin in saccharomyces cerevisiae [PDF]

, 1987
An expression vector utilising the promoter from the yeast phosphoglycerate kinase gene and a complete protein-encoding sequence, was used to direct the expression of the pea seed storage protein, legumin, in yeast (Sciccharomyces cerevisicie) .

Comparing the paths of Hedgehog release in artificial and natural settings

FEBS Letters, EarlyView.
Hh morphogens require solubilization factors to overcome their tight association with the plasma membrane and signal to distant cells, but the precise functions of these factors are controversial. Here, we use published in vivo observations as the most relevant evidence to test their suggested functions and discuss contradictions and gaps between in ...

The type II poly(A)-binding protein PABP-2 is a downstream target of the "let-7" microRNA in the heterochronic pathway of "Caenorhabditis elegans" : mechanisms of microRNA-mediated gene silencing in "Caenorhabditis elegans" [PDF]

, 2012
microRNAs (miRNAs) are a large class of small, non-coding RNAs that post-transcriptionally regulate gene expression in animals, plants and protozoa. miRNAs are genomically encoded and transcribed by RNA polymerase II. Primary transcripts are sequentially
