CDK5-P25 Complex

Dear readers of my blog,

I have to apologize for not being active for a while! I have received many great protein orders and little by little I am working on their realization. But unfortunately, I have a quite tough time this year as the final countdown of my PhD began. I will make up for the missing posts as soon as I can. Thank you for your understanding and patience! Here is a small reward:

Protein Data Bank ID: 1H4L
Protein Name: CDK5-P25 Complex
Organism: Homo sapiens
Title of Drawing: “Baby Dragon Playing with a Toy House“

Cyclin-dependent kinase 5 (CDK5) is an enzyme which triggers the phosphorylation of a key protein of the reelin signaling pathway. Via this pathway CDK5 is involved in neuronal migration and positioning. For its activation CDK5 needs a cofactor, p35 (a fragment of p35 called p25 is shown in the bottom part of this drawing). Recent studies have shown that CDK5 is required already early on during brain development [1].

Similar to ‘playing games’, CDK5 is necessary for a proper development of children’s brain. This baby dragon playing with his toy house illustrates these connections.

    Oh, that is so cute! I think one of my lecturers studies this protein. Good to see you’re back!

    Don’t worry; we can handle a hiatus since you were focusing on the time-consuming responsibility of obtaining a Ph.D. Congrats, by the way! 🙂 I remember how time-consuming it was when I was just getting my MASTERS; so I’m sure this was WAY MORE intense! 🙂 We understand, and WELCOME BACK! 🙂

      Oh, it’s still too early for congratulations as I’m not finished yet. That was rather a notification that I will be absent for some more time… but still thank you for the warm words, and congrats on your masters!:))

    Wow, you have such a wonderful concept. I just stumbled onto your blog with these beautiful renditions of molecules which I didn’t particularly care for last year… your art would’ve inspired happier thoughts about that first semester of biochem!

      Thank you! It really makes me happy to learn that my drawings can trigger some positive feelings for proteins!:)))

        I later showed my friends your pics as we just finished reviewing the cyclin-dependent kinase pathway–they think you’re brilliant!

    What a great post, thanks for sharing.
