PKA
Protein kinase A
PKA (Protein kinase A) is a Ser/Thr phosphoryl transferase that transfers the γ-phosphate group of ATP to protein substrates. PKA phosphorylates more than 100 cytoplasmic and membrane associated targets. PKA mediates a myriad of cellular signaling events and its activity is tightly regulated both in space and time.
PKA is an evolutionarily conserved negative regulator of the hedgehog (Hh) signal transduction pathway. PKA is known to be required for the proteolytic processing event that generates the repressor forms of the Ci and Gli transcription factors that keep target genes off in the absence of Hh.

6-Bnz-cAMP sodium salt
0 Images6-Bnz-cAMP sodium, a derivative of cyclic adenosine monophosphate (cAMP), is a selective PKA activator with inhibitory activity against the bTREK-1 K+ channel. 6-Bnz-cAMP sodium does not activate the Epac signaling pathway. It inhibits the bTREK-1 K+ channel via a voltage-independent, ATP-dependent mechanism that is independent of the PKA/Epac/calmodulin kinase/MAP kinase pathway. 6-Bnz-cAMP sodium activates CREB phosphorylation to regulate osteoblast-specific gene expression, induces osteoblast differentiation, promotes extracellular matrix mineralization, supports osteoblast proliferation, and shows no cytotoxicity toward osteoblasts. It can be used in studies related to bone tissue repair and regeneration. -

Sitagliptin-d4 phosphate
0 ImagesSynonyms: MK-0431-d4 phosphateSitagliptin-d4 phosphate (MK-0431-d4) is the deuterium labeled Sitagliptin phosphate (HY-13749A). Sitagliptin phosphate is an orally active and highly selective DPP4 inhibitor with an IC50 value of 19 nM. Sitagliptin phosphate blocks the degradation of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) by competing inhibition mechanism (Kᵢ = 1 nM), thereby increasing the level of active incretin. Sitagliptin phosphate can also directly stimulate the secretion of GLP-1 by intestinal L cells by activating the cAMP/PKA and ERK1/2 pathways, and this effect is independent of DPP-4. Sitagliptin phosphate shows protective effects on pancreatic islet grafts in 1-type diabetes models. Sitagliptin phosphate can be used for the study of 1-type and 2-type diabetes. -
