Lab #4 Blast: Chum Salmon

1. I didn't search for a
specific protein but, focused my search on salmon as I am currently
volunteering at a local salmon hatchery. Chum Salmon is also monitored by EDCC
with their service learning projects across both Big Gulch and Japanese
Gulch.
2. The protein I chose is
called "N-methyl-D-aspartate receptor 2B," an ion channel protein
found in nerve cells. This protein was a focus in a study to observe the
effects of salinity changes on memory-related genes and hormones in adult chum
salmon (Choi CY et al.)

I think the choice of salmon was ideal because there are many salmons in Washington that are having their habitats destroyed so we should learn more about them. Your choice in protein is also really interesting because the common belief is that fish have memories that last for only several seconds. Although I do not think all fishes have a good memory, it is definitely much longer than just a few seconds. Also, studying this protein would also help us farther understand how salmon are able to return to their birthing grounds after many many years.
ReplyDeleteThis is probably a silly question, but I wonder why it's called a "chum" salmon. I feel like that's either connected to a latin rate or a reference to its sociality, i.e. that type of salmon has a lot of friends. I want to major in neuroscience, so I'm curious about how this protein specifically impacts the memory portion of the brain, like you mentioned. Do you know the answer?
