Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

textIn non-muscle cells, phosphorylation of myosin II regulates actomyosin contractility. The level of myosin phosphorylation depends mainly on the balance of two enzymes, the Ca2+-dependent MLC kinase (MLCK), and myosin phosphatase (MLCP). Phosphorylation of the regulatory light chain of myosin II (MRLC) induces its interaction with actin, activating myosin ATPase and resulting in enhanced cell contractility. Myosin phosphatase decreases MRLC phosphorylation, which inhibits binding to filamentous actin and stress fibre formation (Kimura et al. 1996, Nakai et al. 1997, Katoh et al. 2001, Iwasaki et al. 2001).
