Distinctive Activation Mechanism for Angiotensin Receptor Revealed by a Synthetic Nanobody.

abstract：:The achaete-scute gene complex (AS-C), involved in differentiation of the sensory chaetes of D. melanogaster, and the yellow locus have been cloned. The yellow locus is the most distal and is followed, proximally, by the achaete and the scute loci. In the scute locus (75 kb), three transcription units separated by lon...
