The FGFs are heparin -binding proteins and interactions with cell-surface associated heparan sulfate proteoglycans has been shown to be essential for FGF signal transduction. (beauty104.com.tw)
In our series studies, animal model with severe cell necrosis in testis was created by a 720° testicular torsion for 3 h. (biomedcentral.com)
Dose-dependent increase in glucose uptake activity (GUA) was observed in both cell lines. (wiley.com)

LKB1 itself is a constitutively active kinase, which is regulated by posttranslational modifications and direct binding to phospholipids of the plasma membrane. (sdbonline.org)

This motif is found in Cdc42/Rac-associated proteins such as the protein kinases Pak, MRCK and Ack, the adaptor proteins Spec and WASP, and, in degenerate form, in the kinases MLK, Mekk4, adaptor Par6, scaffold protein IRSp53, and the Borg proteins. (biomedcentral.com)
In this study, we report that Mycobacterium tuberculosis protein Rv3529c exhibits significant similarity to the death domain of the TLR pathway adaptor protein MyD88. (bvsalud.org)

Loss of the Ras GTPase-activating protein neurofibromin promotes nervous system tumor pathogenesis in patients with neurofibromatosis type 1 (NF1). (biomedcentral.com)

We focus on six 'core' effectors that operate in almost all these species - members of the Pak, WASP/WAVE, formin, lipid-kinase, IQGAP and NADPH oxidase families. (biomedcentral.com)
Adipose tissue signals to brain, liver, and muscles to control whole body metabolism through secreted lipid and protein factors as well as neurotransmission, but the mechanisms involved are incompletely understood. (biomed.news)

In this study we have investigated the involvement of PI-3K and its downstream target p70 S6K in the signaling response of corneal epithelial cells after HGF and KGF stimulation. (nih.gov)
Both growth factors also caused the phosphorylation of p70 S6K and stimulation of its activity. (nih.gov)

Based on the phosphoproteomics data, we further examined target relationships of the basophilic kinases AKT, RSK and S6K, which share the substrate recognition motif RxRxxp[ST]. (omicsdi.org)
The phosphoproteomics data were used to define potential targets of the kinases AKT, RSK and S6K, which share the substrate recognition motif RxRxxp[ST]. (omicsdi.org)
It can be difficult to assess the individual functions of each AGC kinase because their substrate specificities are similar. (omicsdi.org)

Autophagy is a fundamental catabolic process coordinated by a network of autophagy-related (ATG) proteins. (babraham.ac.uk)
Conjugation of the Atg8 (autophagy related 8) family of ubiquitin-like proteins to phospholipids of the phagophore is a hallmark of macroautophagy/autophagy. (babraham.ac.uk)
