S-sulfhydration plays a role in synapses and participates in memory formation. H2S participates in memory formation through S-sulfhydration of GAPDH, SR, PKA, PKC, and CaMKII, which may all be related to LTP. AMPAR: α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor; CaMKII: Ca2+/calmodulin-dependent protein kinase II; CBS: cystathionine β-synthase; GluR1: AMPAR subunit; LTP: long-term potentiation; NMDAR: N-methyl-d-aspartate subtype glutamate receptor; PSD95: postsynaptic density 95; Siah: E3 ubiquitin protein ligase; SR: serine racemase.
