Ref(2)P/p62 protein pleomorphism confers tissue-specific function

Yan Yan, Kai Zhang, Gabrielle Pycior…·Kausik Si

One Drosophila Ref(2)P polypeptide takes different structures in midgut and muscle, driving autophagy or mitochondria-associated degradation; deleting disordered region IDR2 switches muscle Ref(2)P to midgut state.

Structural basis for the intestinal protocadherin-based intermicrovillar adhesion complex

Akinobu Senoo, Pablo Adrian Guillen-Poza, Karin Fujishima…·José M. M. Caaveiro

The paper determines the Cryo-EM structure of the intestinal IMAC complex, revealing its heterotetrameric composition and structural features that enable microvilli adhesion and resilience to shear stress.
