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.

commentFUNCTION Actin-binding protein involved in motile and morphological processes. Inhibits actin polymerization, likely by sequestering G-actin. By capping the barbed ends of filaments, it also regulates motility. Seems to play an important role in clathrin-mediated endocytosis and distribution of endocytic organelles. May play a role in regulating the mature length of the middle and short rows of stereocilia (By similarity).SUBUNIT Interacts with G-actin; ADP-actin form and capping protein (CP). May also be able to interact with TWF1 and phosphoinositides, PI(4,5)P2. When bound to PI(4,5)P2, it is down-regulated. Interacts with MYO7A (By similarity).INTERACTION Perinuclear and G-actin-rich cortical actin structure sublocalization.TISSUE SPECIFICITY Ubiquitously expressed (at protein level).PTM In vitro, phosphorylated by PRKCZ, CK2 and SRC.SIMILARITY Belongs to the actin-binding proteins ADF family. Twinfilin subfamily.ONLINE INFORMATION Molecular embrace - Issue 73 of August 2006
