Dendrin

Dendrin is a neural and renal protein whose exact function is still relatively unclear; however, its location in the brain and kidneys is well known as are some of the neural processes it affects. Within the brain, dendrin can be found in neurons and is most notably associated with sleep deprivation. Sleep deprivation causes some areas of the brain dendrin levels to increase, but this increase is insignificant and in total sleep deprivation causes a decrease of the mRNA and protein form of dendrin. Along with two other proteins, MAGI/S-SCAM and α-actinin, dendrin is linked to synaptic plasticity and memory formation in the brain. Nicotine levels have also been shown to have an effect on dendrin expression in the brain. Although unlike sleep deprivation, nicotine increases overall dendrin level. Originally thought to be a brain specific protein, there is now evidence to suggest that dendrin is also found in the kidneys. Dendrin is used to detect glomerulopathy or renal disease, based on its location in the kidneys. Within the kidneys it also works to prevent urinary protein loss. Most studies and information on dendrin pertain specifically to rat or mice brains.
