The Shank protein family Shank proteins, which include Shanks 1, 2 and 3, were first identified in a yeast two-hybrid assay using the gua-nylate kinase-associated protein (GKAP, also called SAPAP1, DLGAP1 and DAP-1) as bait [1]. GKAP is a PSD-95-binding protein that forms an important compo-nent of the postsynaptic density (PSD), where protein-

Lithium May Treat Behavior Linked To Autism Gene - Sciencebeta

27/4/2020 · The mood-stabilizing drug lithium eases repetitive behaviors seen in mice missing SHANK3, an autism gene, according to a new study. The findings[1] suggest lithium merits further study as a treatment for some people with autism, even though the drug has troublesome side effects, including tremors and impaired memory. “Lithium is, of course, a rather difficult, …
