... determination in fruitflies. In structure Tra2 proteins contain two RS domains (domains enriched in arginine and serine residues) flanking a central RRM (RNA recognition motif). Understanding the mechanisms of how Tra2 proteins work to control splicing is one of the key requirements to understand their biology...

... alternative splicing heterogeneous nuclear ribonucleoprotein (hnRNP) nonsense-mediated decay polypyrimidine tract-binding protein (PTB) RNA recognition motif smooth muscle Alternative pre-mRNA splicing is a central mechanism of gene control in metazoan organisms. It allows the production...

... (pentatricopeptide repeat) protein. These are suggested to be major contributors to chloroplast RNA metabolism. Tobacco cpRNPs are composed of five different proteins containing two RNA-recognition motifs and an acidic N-terminal domain. The cpRNPs are abundant proteins and form heterogeneous complexes with most...
