Biochem/physiol Actions

W-13 has also been shown to inhibit the transcytosis of IgA, recycling of transferrin and overall alter the endocytic pathway in Madin-Darby canine kidney cells.
W-13 is a membrane-permeable calmodulin antagonist. W-13 inhibits Ca2+-calmodulin-dependent phosphodiesterase and has been shown to inhibit the EGF-dependent activation of EGFR in N7xHERc fibroblasts.

Group I metabotropic glutamate receptors (mGluR), including mGluR1 and mGluR 5 (mGluR1/5), are coupled to Gq and modulate activity-dependent synaptic plasticity. Direct activation of mGluR1/5 causes protein translation-dependent long-term depression (LTD). Although it has been established that intracellular Ca(2+) and

Ras proteins are small guanosine triphosphatases involved in the regulation of important cellular functions such as proliferation, differentiation, and apoptosis. Understanding the intracellular trafficking of Ras proteins is crucial to identify novel Ras signaling platforms. In this study, we report

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
