Re: [問題] 磷酸化作用

[snark (影燕)]

※ 引述《fim (不空)》之銘言：

【問題】：
Protein phosphorylation is commonly involved with all of the following except

A. Regulation of transcription by extracellular signal molecules.

B. Enzyme activation.

C. Activation of G-protein-linked receptors.

就是這張圖
G-protein-linked receptor desensitization depends on receptor phosphorylation by PKA,PKC, CaMK2 or G-protein-linked receptor kinases(GRKs)
http://219.221.200.61/ywwy/zbsw(E)/edetail6.htm
當然信息傳遞還有很多結束的方式
這只是G-protein-linked receptors desensitization 的方式其中之一
總之信息傳遞有始有終
是每個pathway的重點

D. Activation of receptor tyrosine kinases.

E. Activation of protein kinase molecules.

【問題起因】：
研所普生考古題

【個人看法】：
又到了最不熟的生化時間了
每個都覺得有



謝謝

推 tsubasawolfy:C吧 0.0  GPCR靠ligand結合上去後改變構型
→ fim:我ㄧ開始就是猜Ｃ　　XD
推 freiburg:C
推 xenosdk:C
→ fim:謝謝大家

推 fim:受益良多~那答案究竟...??
推 freiburg:題目是問 "Activation of G-protein-linked receptors."
→ freiburg:這張圖說 "desensitization" depends on phosphorylation
