A novel BR-SMAD is required for larval development in barber’s pole worm Haemonchus contortus
December 23, 2020
The herein presented results show a BMP-like receptor-regulated SMAD in Haemonchus contortus that is required for larval differentiation and underscore an adaptive functional repurposing of BMP-signaling in parasitic worms.
A non-proteolytic function of ubiquitin in transcription repression
July 6, 2014
This article comments on work published by Ndoja et al. (Mol Cell, 2014), which demonstrates that monoubiquitination of some transcription activators can inhibit transcription by recruiting the AAA+ ATPase Cdc48 (also known in metazoans as p97 or VCP), which then extracts the ubiquitinated activator from DNA.
