However, the short isoform of RyR3 is known to be a dominant-negative variant (DN-RyR3), which may negatively regulate functions of both RyR2 and full-length (FL) RyR3 by forming hetero-tetramers. Here, functional roles of RyR3 in the regulation of Ca~(2+) signaling in mesenteric ...
Sirtuin 1 (SIRT1) is involved in both aging and circadian-clock regulation, yet the link between the two processes in relation to SIRT1 function is not clear. UsingSirt1-deficient mice, we found thatSirt1andPeriod 2(Per2) constitute a reciprocal negative regulation loop that plays important ...
This article presents a brief overview of the main biochemical and cellular processes involved in regulation of cyclic GMP production in photoreceptors. The main focus is on how the fluctuations of free calcium concentrations in photoreceptors between light and dark regulate the activity of retinal memb...

negative regulation of RAS activation by the Grb2 splice variant Grb3-3. This plays a tumour-suppressive role by competing with Grb2 to bind Sos. Where Grb3-3 prevails, RTK-induced activation of wild-type MAPK signalling and downstream cellular proliferation is abrogated; including in colon ...
The suppressor of cytokine signaling (SOCS) family of proteins has been implicated in the negative regulation of several cytokine pathways, particularly the receptor-associated tyrosine kinase/signal transducer and activator of transcription (Jak/STAT) pathways of transcriptional activation. SOCS-1 (also ...
oppositely regulated (Figure 14D). In addition, the negative regulation of miR-148a-5p by TLR3 may be one of the reasons for the low expression of miR-148a-5p after DTMUV infection, but more experiments are required to explore the mechanism by how TLR3 negatively regulates miR-148a-5p....
The purpose of current work is to functionally integrate both tailorable CTE as well as tunable PR in one metastructure. Thus, as shown in Fig. 2c, straightforwardly, we originally devise the hybrid cellular metastructure, i.e., triangle arrow (TA) CDBEA which is the serial connection of ...

of key proteins. However, as proteolysis is an irreversible process, it is subject to tight regulation of substrate binding and degradation. Here we review the roles of the proteolytic enzymes in Gram-negative bacteria and how these enzymes can be regulated to target only a subset of proteins....
