USP46 deubiquitinates GRIA. 5 / 5
| 5

reach
"Together, these data reveal a conserved mechanism where USP46 deubiquitinates AMPARs at synapses to protect them from degradation and promote their recycling to the cell surface to affect synapse function."

reach
"Endogenous USP46 suppresses AMPAR ubiquitination in neurons."

reach
"We found that USP46 suppressed AMPAR ubiquitination leading to an increase in receptor protein amount as well as in receptor synaptic localization."

reach
"Given the same type of deubiquitinating enzyme (USP46) is able to deubiquitinate AMPA receptors, and knockdown of USP46 elevated AMPA receptor ubiquitination and reduced AMPA receptor expression in hi[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"USP46 over-expression leads to a reduction in AMPAR ubiquitination, whereas knockdown of USP46 by either siRNAs or shRNAs causes a significant increase in AMPAR ubiquitination."
