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 Although its physiological function is unclear, it can inhibit neutrophil cathepsin G and mast cell chymase, both of which can convert angiotensin-1 to the active angiotensin-2.SUBUNIT Interacts with DNAJC1.INTERACTION Plasma. Synthesized in the liver. Like the related alpha-1-antitrypsin, its concentration increases in the acute phase of inflammation or infection. Found in the amyloid plaques from the hippocampus of Alzheimer disease brains.DOMAIN The reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the carboxyl group of the serpin reactive site and the serine hydroxyl of the protease. The resulting inactive serpin-protease complex is highly stable.PTM N- and O-glycosylated.MISCELLANEOUS Alpha-1-antichymotrypsin can bind DNA.SIMILARITY Belongs to the serpin family.CAUTION It is uncertain whether Met-1 or Met-4 is the initiator.SEQUENCE CAUTION Extended N-terminus.SEQUENCE CAUTION Extended N-terminus.SEQUENCE CAUTION Extended N-terminus.ONLINE INFORMATION Alpha-1 antichymotrypsin entry
