G蛋白αs亚基(G protein alpha s subunit, Gαs)蛋白的异常激活参与多种疾病的发生和发展,包括垂体瘤、胰腺癌等。靶向Gαs 蛋白的短线性肽已被证明具有Gα蛋白的核苷酸态选择性,且能够结合到Gα的Switch II/α3口袋。然而,线性肽细胞通透性差且在细胞中不稳定,不能作为药物发现的理想分子。由于环肽具备环化的...

(GDP). The G proteins that associate with GPCRs are heterotrimeric, meaning they have three different subunits: an alpha subunit, a beta (β) subunit, and a gamma (γ) subunit. Two of these subunits - alpha (α-) and gamma (γ) - are attached to the plasma membrane by lipid anchors...
High affinity interactions of beta gamma with either G protein alpha subunits or effector molecules require that the gamma subunit be prenylated. Furthermore, it appears from this study that prenylation may play a crucial role in mediating the association between beta gamma and other proteins[2]. ...
the expression of the alpha subunit of Gi was not detected by in situ hybridization (Additional file3: Fig. S3). In contrast, the expression of the alpha subunit of Go type G protein (limGαo), a type of the Gi subgroup, was detected by in situ hybridization (Fig.3b, c). The pro...
a constitutively active gα subunit provide insights into the mechanism of g protein activation nih public access author manuscript G Singh,S Ramachandran,RA Cerione 被引量: 0发表: 2019年 Studies of a constitutively active G-alpha subunit provide insights into the mechanism of G protein activation...
G(z) couples to most of the known G(i)-linked receptors and its alpha subunit (Galpha(z)) inhibits adenylyl cyclases as efficiently as Galpha(i) subtypes. A series of chimeric Galpha subunits with different portions of Galpha(z) and Galpha(t1) (a regulator of cGMP phosphodiesterase) ...
G-proteins are implicated in plant productivity, but their genome-wide roles in regulating agronomically important traits remain uncharacterized. Transcriptomic analyses of rice G-protein alpha subunit mutant (rga1) revealed 2270 differentially expressed genes (DEGs) including those involved in C/N and ...
(Fig.1a, lane 1 and Fig.1b). In contrast, the displaced alpha subunit of Gt(Gαt) was found in the flow-through (Fig.1a, lane 2). Interestingly, similar results were obtained in the absence of either Rh* or Rh* and GTP during the purification (Fig.1a, lanes 3–6). Moreover,...
