Missing mechanism helps solve fragile X protein mystery

by  /  24 January 2023

Cells from people with fragile X syndrome overproduce — but don’t accumulate — proteins. New work suggests that excessive protein breakdown may account for this discrepancy, and explain some of the syndrome’s traits.

Location prompts fragile X protein to flip its function

by  /  31 January 2022

The protein, FMRP, shapes cell signaling near synapses but switches to regulate genes in the cell body, according to new research.
