Ubiquitin is an intracellular signalling molecule that is conjugated to various proteins. Ubiquitin conjugation to itself yields Lys- or Met-conjugated chains, thus expanding its repertoire of ...

Protein domains that bind ('read') histones bearing specific post-translational modifications are frequently physically coupled to enzymes that catalyse the addition ('writer') or removal ('eraser') ...

We study the Dirichlet problem for discrete harmonic functions in unbounded product domains on multidimensional lattices. First we prove some versions of the Phragmén-Lindelöf theorem and use Fourier ...
