NAD synthase nicotinamide mononucleotide adenylyltransferase is a stress-response protein that acts as a chaperone for neuronal maintenance and protection
-
-
-
additional information
?
-
-
NAD synthase nicotinamide mononucleotide adenylyltransferase displays chaperone function both in biochemical assays and cultured cells. It is upregulated in the brain upon overexpression of poly-glutamine expanded protein and recruited with the chaperone Hsp70 into protein aggregates.
