Arthropod Struct Dev. 2004 Apr;33(2):161-72. doi: 10.1016/j.asd.2004.01.001.

We characterize morphological and histochemical changes occurring within the oocyte nucleus (germinal vesicle) during oogenesis in two phthirapteran species: the pig louse, Haematopinus suis (Anoplura) and the pigeon louse, Columbicola columbae (Mallophaga). In previtellogenic oocytes, within the oocyte nucleus...

2-D DIGE identification of differentially expressed heterogeneous nuclear ribonucleoproteins and transcription factors during neural differentiation of human embryonic stem cells.

Proteomics. Clinical applications

The human immunodeficiency virus type 1 (HIV-1) unspliced, 9 kb genomic RNA (vRNA) is exported from the nucleus for the synthesis of viral structural proteins and enzymes (Gag and Gag/Pol) and is then transported to sites of virus assembly...

Malleable ribonucleoprotein machine: protein intrinsic disorder in the Saccharomyces cerevisiae spliceosome.

PeerJ

Coelho Ribeiro Mde L, Espinosa J, Islam S, Martinez O, Thanki JJ, Mazariegos S, Nguyen T, Larina M, Xue B, Uversky VN.
PMID: 23638354
PeerJ. 2013 Feb 12;1:e2. doi: 10.7717/peerj.2. Print 2013.

Recent studies revealed that a significant fraction of any given proteome is presented by proteins that do not have unique 3D structures as a whole or in significant parts. These intrinsically disordered proteins possess dramatic structural and functional variability,...
