methyl 2-(4-methoxyphenyl)-3-methyl-4-oxo-3,4-dihydro[1]benzopyrano[3,4-b]pyrrole-1-carboxylate | i.e. pyrcoumin, a pyrrolocoumarin, and a competitive inhibitor of dCTP pyrophosphatase 1 (dCTPP1). Pyrcoumin induces thermal stabilization of dCTPP1 with a shift in melting temperature of 6°C with a half-maximal effective concentration (EC50) of 0.0059 mM. 57% inhibition. Pyrcoumin impairs the direct interaction of dCTPP1 and ubiquitin carboxyl-terminal hydrolase (USP7, EC 3.4.19.12) | Homo sapiens | |

General Information | Comment | Organism |
---|---|---|
metabolism | dCTPP1 plays a role in regulation of Wnt/bcatenin signaling most likely through a direct interaction with USP7. Canonical Wnt/beta-catenin signaling is a fundamental growth control pathway essential for, for example, embryonic development, stem cell maintenance, cell proliferation and tissue homeostasis, pathway regulation, overview. Upon activation the central Wnt pathway component beta-catenin is no longer phosphorylated and degraded by the so-called destruction complex, but rather stabilized and translocated to the nucleus, where it activates the expression of Wnt target genes | Homo sapiens |
physiological function | the canonical Wnt pathway is essential for normal embryonic development and tissue homeostasis, and its deregulation plays a crucial role in carcinogenesis. dCTP pyrophosphatase 1 (dCTPP1) is a positive regulator of canonical Wnt signaling, interacts with ubiquitin carboxyl-terminal hydrolase (USP7, EC 3.4.19.12) in Wnt signal-dependent manner, and this interaction is weakened by dCTPP1 inhibitors, e.g. pyrcoumin. Analysis of interaction between dCTPP1 and USP7 and the role for dCTPP1 in the Wnt/beta-catenin pathway, overview | Homo sapiens |
