HAPPY BIRTHDAY, CLINKSHRINK!!!!
I'm told the theme is "fungus." I'm working on it.Love,Dinah
Thanks everybody! I think I should share my horoscope for today:
Taurus (April 20-May 20): You're a bit of a provocateur. Sometimes it's reassuring when others have a big reaction to you. It means that you're really being heard.
Fungal Galectins, Sequence and Specificity of Two Isolectins from Coprinus cinereus

Galectins are members of a genetically related family of beta -galactoside-binding lectins. At least eight distinct mammalian galectins have been identified. More distantly related, but still conserving amino acid residues critical for carbohydrate-binding, are galectins in chicken, eel, frog, nematode, and sponge. Here we report that galectins are also expressed in a species of fungus, the inky cap mushroom, Coprinus cinereus. Two dimeric galectins are expressed during fruiting body formation which are 83% identical to each other in amino acid sequence and conserve all key residues shared by members of the galectin family. Unlike most galectins, these have no N-terminal post-translational modification and no cysteine residues. We expressed one of these as a recombinant protein and studied its carbohydrate-binding specificity using a novel nonradioactive assay. Binding specificity has been well studied for a number of other galectins, and like many of these, the recombinant C. cinereus galectin shows particular affinity for blood group A structures. These results demonstrate not only that the galectin gene family is evolutionarily much older than previously realized but also that fine specificity for complex saccharide structures has been conserved. Such conservation implies that galectins evolved to perform very basic cellular functions, presumably by interaction with glycoconjugates bearing complex lactoside carbohydrates resembling blood group A.

Provocative? Who, me?
Thematic joke:
ReplyDeleteWhat did the greeter say to the mushroom when he went to the party?
(you look like a "fun guy")
Happy Birthday.
Happy Birthday!
ReplyDeleteHappy Birthday! Hope it was a good one! :)
ReplyDeleteTake care,
Carrie :)
For your birthday; a list of the my favorite anagrams for "psychiatrist."
ReplyDeleteI sit spy chart
Psych, art it is
At psych I stir
Frohliche Geburtstag!
FUNGUS????
ReplyDeleteI don't get the mushrooms, but I hope they were enjoyed!
ReplyDeleteHappy birthday.
Happy (belated)birthday, Clink!
ReplyDeleteJust an abstract, but it's the closest to the subject matter I could get.

Thanks again everybody!

And for everybody wondering what's up with me and mushrooms, it's a reference to my post from last year Call Of The Wild.
