Cool new paper from the Munro lab!
The small #GTPase Rab1 is a master regulator of #Golgi traffic and #autophagy. van Vliet, Munro et al. @mrclmb.bsky.social performed a proteomic screen to identify novel Rab1 effectors, including a #dynein motor adaptor and cargo receptors for autophagy. rupress.org/jcb/article/...

Very sad news indeed…
John Gurdon, former Group Leader and Head of @cellbiol-mrclmb.bsky.social has died.
Despite calling himself a "total non-intellectual” his work to reprogramme somatic cells to pluripotent stem cells transformed the field of developmental biology.

For something as classic as the Spemann-Mangold organizer first discovered in amphibians, the existence of such an organiser in mammals remains elusive. In this thought provoking review by Kate Mcdole et al, they discuss the evidence for and against such organiser in mouse.
