Structural basis for methylarginine-dependent recognition of Aubergine by Tudor.

Piwi proteins are modified by symmetric dimethylation of arginine (sDMA), and the methylarginine-dependent interaction with Tudor domain proteins is critical for their functions in germline development. Cocrystal structures of an extended Tudor domain (eTud) of Drosophila Tudor with methylated peptides of Aubergine, a Piwi family protein, reveal that sDMA is recognized by an asparagine-gated ar...

Structural basis for recognition of arginine methylated Piwi proteins by the extended Tudor domain.

Arginine methylation modulates diverse cellular processes and represents a molecular signature of germ-line-specific Piwi family proteins. A subset of Tudor domains recognize arginine methylation modifications, but the binding mechanism has been lacking. Here we establish that, like other germ-line Tudor proteins, the ancestral staphylococcal nuclease domain-containing 1 (SND1) polypeptide is e...

Elective affinities: a Tudor-Aubergine tale of germline partnership.

In Drosophila melanogaster and many other metazoans, the specification of germ cells requires cytoplasmic inheritance of maternally synthesized RNA and protein determinants, which are assembled in electron-dense cytoplasmic structures known as germ or polar granules, found at the posterior end of the oocytes. Recent studies have shown that the formation of germ granules is dependent on the inte...

Structural basis for DNA recognition by STAT6.

STAT6 participates in classical IL-4/IL-13 signaling and stimulator of interferon genes-mediated antiviral innate immune responses. Aberrations in STAT6-mediated signaling are linked to development of asthma and diseases of the immune system. In addition, STAT6 remains constitutively active in multiple types of cancer. Therefore, targeting STAT6 is an attractive proposition for treating related...

Structural basis for spectrin recognition by ankyrin.

Maintenance of membrane integrity and organization in the metazoan cell is accomplished through intracellular tethering of membrane proteins to an extensive, flexible protein network. Spectrin, the principal component of this network, is anchored to membrane proteins through the adaptor protein ankyrin. To elucidate the atomic basis for this interaction, we determined a crystal structure of hum...
