Overactive Signaling Leads to Abnormal Synapses in Fragile X Syndrome (2 of 2)

image: Loss of FMR1 leads to increased BMPR2 abundance. (A) In wild-type neurons, FMRP represses BMPR2, which limits LIMK1 activation and promotes actin depolymerization. (B) In FMRP mutant neurons, BMPR2 levels increase, which drives LIMK1 activation and reduces actin polymerization. This material relates to a paper that appeared in the June 7, 2016, issue of Science Signaling, published by AAAS. The paper, by R. Kashima at University of California, San Francisco in San Francisco, Calif., and colleagues was titled, "Augmented noncanonical BMP type II receptor signaling mediates the synaptic abnormality of fragile X syndrome." view more
